The United States Drug Enforcement Administration (DEA) maintains lists regarding the classification of illicit drugs (see DEA Schedules). It also maintains List I of chemicals and List II of chemicals, which contain chemicals that are used to manufacture the controlled substances/illicit drugs. The list is designated within the Controlled Substances Act but can be modified by the U.S. Attorney General as illegal manufacturing practices change.
Although the list is controlled by the Attorney General, the list is considered a DEA list because the DEA publishes and enforces the list.
Suppliers of these products are subject to regulation and control measures:
== List I chemicals ==
These chemicals are designated as those that are used in the manufacture of the controlled substances and are important to the manufacture of the substances:
== List II chemicals ==
These chemicals are designated as those that are used in the manufacture of controlled substances:
== Special Surveillance List ==
=== Chemicals ===
All listed chemicals as specified in 21 CFR 1310.02 (a) or (b). This includes supplements which contain a listed chemical, regardless of their dosage form or packaging and regardless of whether the chemical mixture, drug product or dietary supplement is exempt from regulatory controls. For each chemical, its illicit manufacturing use is given in parentheses. Some Special Surveillance List chemicals do not have an exclusive manufacturing use for a specific illicit drug but rather have a broad range of uses in both legitimate and illicit manufacturing operations.
=== Equipment ===
The equipment list:
22-liter heating mantles
Encapsulating machines
Hydrogenators
Tableting machines, including punches and dies

title: "E number"

E numbers, short for Europe numbers, are codes for substances used as food additives, including those found naturally in many foods, such as vitamin C, for use within the European Union (EU) and European Free Trade Association (EFTA). Commonly found on food labels, their safety assessment and approval are the responsibility of the European Food Safety Authority (EFSA). The fact that an additive has an E number implies that its use was at one time permitted in products for sale in the European Single Market; some of these additives are no longer allowed today.
Having a single unified list for food additives was first agreed upon in 1962 with food colouring. In 1964, the directives for preservatives were added; In 1970 antioxidants were added; In 1974 emulsifiers, stabilisers, thickeners and gelling agents were added as well.
== Numbering schemes ==
The numbering scheme follows that of the International Numbering System (INS) as determined by the Codex Alimentarius committee, though only a subset of the INS additives are approved for use in the European Union as food additives. Outside the European continent plus Russia, E numbers are also encountered on food labelling in other jurisdictions, including the Gulf Cooperation Council, South Africa, Australia, New Zealand, Malaysia, Hong Kong, and India.
== Colloquial use ==
In some European countries, the "E number" is used informally as a derogatory term for artificial food additives. For example, in the UK, food companies are required to include the "E number(s)" in the ingredients that are added as part of the manufacturing process. Many components of naturally occurring healthy foods and vitamins have assigned E numbers (and the number is a synonym for the chemical component), e.g. vitamin C (E300) and lycopene (E160d), found in carrots. At the same time, "E number" is sometimes misunderstood to imply approval for safe consumption. This is not necessarily the case, e.g. Avoparcin (E715) is an antibiotic once used in animal feed, but is no longer permitted in the EU, and has never been permitted for human consumption. Sodium nitrite (E250) is toxic. Sulfuric acid (E513) is caustic.
== Classification by numeric range ==
Not all examples of a class fall into the given numeric range; moreover, certain chemicals (particularly in the E400499 range) have a variety of purposes.
== Full list ==
The list shows all components that have an E-number assigned, even those no longer allowed in the EU.
=== E100E199 (colours) ===
=== E200E299 (preservatives) ===
=== E300E399 (antioxidants, acidity regulators) ===
=== E400E499 (thickeners, stabilisers, emulsifiers) ===
=== E500E599 (acidity regulators, anti-caking agents) ===
=== E600E699 (flavour enhancers) ===
=== E700E799 (antibiotics) ===
=== E900E999 (glazing agents, gases and sweeteners) ===

An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups. In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify chemical compounds based on the way infrared radiation is absorbed by the compound.
The absorptions in this range do not apply only to bonds in organic molecules. IR spectroscopy is useful when it comes to analysis of inorganic compounds (such as metal complexes or fluoromanganates) as well.

Tables of vibrational transitions of stable and transient molecules are also available.

The International Numbering System for Food Additives (INS) is an international naming system for food additives, aimed at providing a short designation of what may be a lengthy actual name. It is defined by Codex Alimentarius, the international food standards organisation of the World Health Organization (WHO) and Food and Agriculture Organization (FAO) of the United Nations (UN). The information is published in the document Class Names and the International Numbering System for Food Additives, first published in 1989, with revisions in 2008 and 2011. The INS is an open list, "subject to the inclusion of additional additives or removal of existing ones on an ongoing basis".
== Numbering system ==
INS numbers consist of three or four digits, optionally followed by an alphabetical suffix to further characterize individual additives. On packaging in the European Union (EU), approved food additives are written with a prefix of E. An additive that appears in the INS does not automatically have a corresponding E number.
INS numbers are assigned by the committee to identify each food additive. INS numbers generally correspond to E numbers for the same compound, e.g. INS 102, Tartrazine, is also E102. INS numbers are not unique and, in fact, one number may be assigned to a group of similar compounds.
== List of INS numbers ==
Except where stated, the list of INS numbers and associated food additives is based on the most recent publication of the Codex Alimentarius, Class Names and the International Numbering System for Food Additives, first published in 1989, with revisions in 2008 and 2011.
E number and American approval flags are derived from other sources.
In the table below, food additives approved for the EU are listed with an 'E', and those approved for Australia and New Zealand with an 'A'. and for the US with a U, even though the US does not use the INS numbering system.

The NA numbers (North American Numbers) are assigned by the United States Department of Transportation, supplementing the larger set of UN numbers, for identifying hazardous materials. NA numbers largely duplicate UN numbers, however a selection of additional numbers are provided for materials that are not covered by UN numbers as a hazardous material. In a couple of instances NA numbers provide an alternative description than the equivalent UN number.

Many synthetic cannabinoids were designed by Stargate International, a now defunct New Zealand company in the 2000s and 2010s, and feature an alphanumeric code beginning with the prefix "SGT". PB-22 (SGT-21) is credited with being the first synthetic cannabinoid to feature a quinoline substructure with an ester linker at the indole 3-position. The mainly N-cumyl-indazole-3-carboxamide derivatives are best known. Many SGT compounds are banned as designer drugs in various jurisdictions, such as Japan.

Schedule 1 substances, in the sense of the Chemical Weapons Convention, are chemicals which are feasible either to be used directly as chemical weapons or in the manufacture of chemical weapons, and which have very limited to no use outside of chemical warfare. These may be produced or used for research, medical, pharmaceutical or chemical weapon defence testing (called "protective testing" in the treaty) purposes but production above 100 grams per year must be declared to the OPCW in accordance with Part VI of the "Verification Annex". A country is limited to possessing a maximum of one tonne of these materials.
Schedule 1 is divided into Part A substances, which are chemicals that can be used directly as weapons, and Part B which are precursors useful in the manufacture of chemical weapons. Examples are mustard and nerve agents, and substances which are solely used as precursor chemicals in their manufacture. A few of these chemicals have very small-scale non-military applications; for example, minute quantities of nitrogen mustard are used to treat certain cancers.
The Schedule 1 list is one of three lists. Chemicals which are feasible to use as weapons, and their precursors, but which have legitimate applications as well are listed in Schedule 2 (small-scale applications) and Schedule 3 (large-scale applications). The use of Schedule 1, 2, or 3 chemicals as weapons is banned by the Convention.
== Guidelines for Schedule 1 ==
The following criteria shall be taken into account in considering whether a toxic chemical or precursor should be included in Schedule 1:
It has been developed, produced, stockpiled or used as a chemical weapon as defined in Article II;
It poses otherwise a high risk to the object and purpose of this Convention by virtue of its high potential for use in activities prohibited under this Convention because one or more of the following conditions are met:
It possesses a chemical structure closely related to that of other toxic chemicals listed in Schedule 1, and has, or can be expected to have, comparable properties;
It possesses such lethal or incapacitating toxicity as well as other properties that would enable it to be used as a chemical weapon;
It may be used as a precursor in the final single technological stage of production of a toxic chemical listed in Schedule 1, regardless of whether this stage takes place in facilities, in munitions or elsewhere;
It has little or no use for purposes not prohibited under this Convention.

Schedule 2 substances, in the sense of the Chemical Weapons Convention, are chemicals that are feasible to use as chemical weapons themselves (Part A), or their manufacturing precursors (Part B), and which have small-scale applications outside of chemical warfare and so can be legitimately manufactured in small quantities. An example is thiodiglycol, which can be used in the manufacture of mustard agents but is also used as a solvent in inks. Manufacture must be declared as their production is subject to declaration to the Organisation for the Prohibition of Chemical Weapons (OPCW) per Part VII of the "Verification Annex", and they may not be exported to countries that are not party to the Convention.
The Schedule 2 list is one of three lists. Chemicals that can be used as weapons, or used in their manufacture, but that have no, or almost no, legitimate applications as well are listed in Schedule 1, whilst Schedule 3 is used for chemicals that also have widespread industrial uses. The use of Schedule 1, 2, or 3 chemicals as weapons is banned by the convention.
== Guidelines for Schedule 2 ==
Schedule 2 lists toxic chemicals and precursors not listed in Schedule 1 that are deemed to pose a significant risk to be used as a chemical weapon, or may be important for the production of any of the chemicals listed in Schedule 1. They are not produced in large quantities for commercial or other purposes not prohibited by the Convention and may be used for those purposes in limited quantities.
The listed chemicals are subjected to the following criteria:
It poses a significant risk to the object and purpose of this Convention because it possesses such lethal or incapacitating toxicity as well as other properties that could enable it to be used as a chemical weapon;
It may be used as a precursor in one of the chemical reactions at the final stage of formation of a chemical listed in Schedule 1 or Schedule 2, part b
It poses a significant risk to the object and purpose of this Convention by virtue of its importance in the production of a chemical listed in Schedule 1 or Schedule 2, part A;
It is not produced in large commercial quantities for purposes not prohibited under this Convention.
== Toxic chemicals ==
Amiton: O,O-Diethyl S-(2-(diethylamino)ethyl)phosphorothiolate and corresponding alkylated or protonated salts
PFIB: 1,1,3,3,3-Pentafluoro-2-(trifluoromethyl)-1-propene
3-Quinuclidinyl benzilate (BZ)
== Precursors ==
Chemicals, except for those listed in Schedule 1, containing a phosphorus atom to which is bonded one methyl, ethyl or propyl (normal or iso) group but not further carbon atoms, e.g.
Methylphosphonyl dichloride
Dimethyl methylphosphonate
Exemption: Fonofos: O-Ethyl S-phenyl ethylphosphonothiolothionate
N,N-Dialkyl (Me, Et, n-Pr or i-Pr) phosphoramidic dihalides
Dialkyl (Me, Et, n-Pr or i-Pr) N,N-dialkyl (Me, Et, n-Pr or i-Pr)-phosphoramidates
Arsenic trichloride
2,2-diphenyl-2-hydroxyacetic acid
Quinuclidin-3-ol
N,N-Dialkyl (Me, Et, n-Pr or i-Pr) aminoethyl-2-chlorides and corresponding protonated salts
N,N-Dialkyl (Me, Et, n-Pr or i-Pr) aminoethane-2-ols and corresponding protonated salts
Exemptions: N,N-Dimethylaminoethanol and corresponding protonated salts; N,N-Diethylaminoethanol and corresponding protonated salts
N,N-Dialkyl (Me, Et, n-Pr or i-Pr) aminoethane-2-thiols and corresponding protonated salts
Thiodiglycol: Bis(2-hydroxyethyl)sulfide

Schedule 3 substances, in the sense of the Chemical Weapons Convention, are chemicals which have large-scale industrial uses, but are feasible to use as toxic chemical weapons (Part A) or manufacturing precursors (Part B).
Plants which manufacture more than 30 tonnes per year must be declared and can be inspected as per Part VIII of the "Verification Annex", and there are restrictions on export to countries which are not CWC signatories. Examples of these substances are phosgene, which has been used as a chemical weapon but which is also a precursor in the manufacture of many legitimate organic compounds, and triethanolamine, used in the manufacture of nitrogen mustard but also commonly used in toiletries and detergents.
The Schedule 3 list is one of three lists. Chemicals which can be used as weapons, or used in their manufacture, but which have no, or almost no, legitimate applications as well are listed in Schedule 1, whilst Schedule 2 is used for chemicals which have legitimate small-scale applications. The use of Schedule 1, 2, or 3 chemicals as weapons is banned by the Convention.
== Guidelines for Schedule 3 ==
The criteria for including a chemical in this schedule is that it is not listed in either of the other two, and:
It has been produced, stockpiled or used as a chemical weapon;
It poses otherwise a risk to the object and purpose of the Convention because it possesses such lethal or incapacitating toxicity as well as other properties that might enable it to be used as a chemical weapon;
It poses a risk to the object and purpose of the Convention by virtue of its importance in the production of one or more chemicals listed in Schedule 1 or Schedule 2, part B;
It may be produced in large commercial quantities for purposes not prohibited under the Convention.
== Toxic chemicals ==
Phosgene: Carbonyl dichloride
Cyanogen chloride
Hydrogen cyanide
Chloropicrin: Trichloronitromethane
== Precursors ==
Phosphorus oxychloride
Phosphorus trichloride
Phosphorus pentachloride
Trimethyl phosphite

This is a static list of 599 additives that could be added to tobacco cigarettes in 1994. The ABC News program Day One first released the list to the public on March 7, 1994. It was submitted to the United States Department of Health and Human Services in April 1994. They are also listed in the documents that are part of the 1998 Tobacco Master Settlement Agreement. It applies, as documented, only to American manufactured cigarettes intended for distribution within the United States by the listed companies. The five major tobacco companies that reported the information were:
American Tobacco Company
Brown and Williamson
Liggett Group, Inc.
Philip Morris Inc.
R.J. Reynolds Tobacco Company
One significant issue is that while all these chemical compounds have been approved as additives to food, they were not tested by burning. Burning changes the properties of chemicals. Burning creates additional toxic compounds, including carcinogens. According to the U.S. National Cancer Institute: "Of the more than 7,000 chemicals in tobacco smoke, at least 250 are known to be harmful, including hydrogen cyanide, carbon monoxide, and ammonia. Among the 250 known harmful chemicals in tobacco smoke, at least 69 can cause cancer." See: Health effects of tobacco smoking and List of cigarette smoke carcinogens.
Although many of these additives are used in making cigarettes, each cigarette does not contain all of these additives. Some of these additives are found in cigarettes outside the USA too.
Some American brands are sold in other nations. For example: Marlboro, L&M, Winston, Chesterfield, Kent, and Newport.

The differences between additives for fracking in different countries are the type of chemicals used (hazardous, non-hazardous), the disclosure of chemicals and the composition of fracturing fluid. In 2010, Halliburton announced the creation of food additive based hydraulic fracturing fluid in response to calls for transparency and demand for a "more environmentally friendly" unconventional hydrocarbon production.
== Europe ==
In Europe, Poland, Norway and Germany have the largest reserves of shale gas, and drillings are underway.
== United Kingdom ==
In the United Kingdom, the environmental regulator permits only chemical additives which are classed as non hazardous to groundwater for fracturing fluids. Operators are required to disclose the content of hydraulic fracturing fluids to the relevant environment agency while the composition must be disclosed if the regulator demands it. The permitted additives for hydraulic fracturing fluid include polycrylamide, hydrochloric acid and a biocide.
== United States ==
In the US, about 750 compounds have been listed as additives for hydraulic fracturing, also known as ingredients of pressurized fracking fluid, in an industry report to the US Congress in 2011 The following is a partial list of the chemical constituents in additives that are used or may have been used in fracturing operations.

When heated, ammonium nitrate decomposes non-explosively into nitrous oxide and water vapor; however, it can be induced to decompose explosively by detonation into oxygen, nitrogen, and water vapor. Large stockpiles of the material can be a major fire risk due to their supporting oxidation, and may also detonate, as happened in the Texas City disaster of 1947 which led to major changes in the regulations for storage and handling.
There are two major classes of incidents resulting in explosions:
In the first case, the explosion happens by the shock induced detonation. The initiation happens by an explosive charge going off in the mass, by the detonation of a shell thrown into the mass, or by detonation of an explosive mixture in contact with the mass. Examples are Kriewald, Morgan, Oppau, Tessenderlo, and Traskwood.
In the second case, the explosion results from a fire that spreads into the ammonium nitrate (AN) itself (Texas City, Brest, Tianjin, Beirut) or to a mixture of an ammonium nitrate with a combustible material during the fire. The fire must be confined at least to a degree for successful transition from a fire to an explosion (a phenomenon known as "deflagration to detonation transition", or DDT). Pure, compact AN is stable and very difficult to initiate.
Ammonium nitrate decomposes in temperatures above 169 °C (336 °F). Pure AN is stable and will stop decomposing once the heat source is removed, but when catalysts are present, the reaction can become self-sustaining (known as self-sustaining decomposition, or SSD). This is a well-known hazard with some types of NPK fertilizers and is responsible for the loss of several cargo ships.
== Timeline of major incidents ==
The column AN states the amount of ammonium nitrate consumed in the disaster in metric tonnes.

This is a list of antioxidants naturally occurring in food. Vitamin C and vitamin E which are ubiquitous among raw plant foods are confirmed as dietary antioxidants, whereas vitamin A becomes an antioxidant following metabolism of provitamin A beta-carotene and cryptoxanthin. Most food compounds listed as antioxidants such as polyphenols common in colorful, edible plants have antioxidant activity only in vitro, as their fate in vivo is to be rapidly metabolized and excreted, and the in vivo properties of their metabolites remain poorly understood. For antioxidants added to food to preserve them, see butylated hydroxyanisole and butylated hydroxytoluene.
== Regulatory guidance ==
In the following discussion, the term "antioxidant" refers mainly to non-nutrient compounds in foods, such as polyphenols, which have antioxidant capacity in vitro and so provide an artificial index of antioxidant strength the oxygen radical absorbance capacity (ORAC) measurement. Other than for dietary antioxidant vitamins vitamin A, vitamin C, and vitamin E no food compounds have been proved to be antioxidants in vivo. Accordingly, regulatory agencies such as the Food and Drug Administration of the United States and the European Food Safety Authority (EFSA) have published guidance disallowing food product labels to claim an inferred antioxidant benefit when no such physiological evidence exists.
== Physiological context ==
Despite the above discussion implying that ORAC-rich foods with polyphenols may provide antioxidant benefits when in the diet, there remains no physiological evidence that any polyphenols have such actions or that ORAC has any relevance in the human body.
On the contrary, research indicates that although polyphenols are antioxidants in vitro, antioxidant effects in vivo are probably negligible or absent. By non-antioxidant mechanisms still undefined, polyphenols may affect mechanisms of cardiovascular disease or cancer.
The increase in antioxidant capacity of blood seen after the consumption of polyphenol-rich (ORAC-rich) foods is not caused directly by the polyphenols, but most likely results from increased uric acid levels derived from metabolism of flavonoids. According to Frei, "we can now follow the activity of flavonoids in the body, and one thing that is clear is that the body sees them as foreign compounds and is trying to get rid of them." Another mechanism may be the increase in activities of paraoxonases by dietary antioxidants that can reduce oxidative stress.
== Vitamins ==
Vitamin A (retinol), also synthesized by the body from beta-carotene, protects dark green, yellow, and orange vegetables and fruits from solar radiation damage, and is thought to play a similar role in the human body. Carrots, squash, broccoli, sweet potatoes, tomatoes (which gain their color from the compound lycopene), kale, mangoes, oranges, seabuckthorn berries, wolfberries (goji), collards, cantaloupe, peaches, and apricots are particularly rich sources of beta-carotene, the major provitamin A carotenoid.
Vitamin C (ascorbic acid) is a water-soluble compound that fulfills several roles in living systems. Sources include citrus fruits (such as oranges, sweet lime, etc.), green peppers, broccoli, green leafy vegetables, black currants, strawberries, blueberries, seabuckthorn, raw cabbage, and tomatoes.
Vitamin E, including tocotrienol and tocopherol, is fat soluble and protects lipids. Sources include wheat germ, seabuckthorn, nuts, seeds, whole grains, green leafy vegetables, kiwifruit, vegetable oil, and fish-liver oil. Alpha-tocopherol is the main form in which vitamin E is consumed. Recent studies showed that some tocotrienol isomers have significant anti-oxidant properties.
== Vitamin cofactors and minerals ==
Coenzyme Q10
Manganese, particularly when in its +2 valence state as part of the enzyme called superoxide dismutase (SOD)
Iodide
== Hormones ==
Melatonin
== Carotenoid terpenoids ==
Alpha-carotene - found in carrots, winter squash, tomatoes, green beans, cilantro, Swiss chard
Astaxanthin - found naturally in red algae and animals higher in the marine food chain. It is a red pigment familiarly recognized in crustacean shells as well as salmon flesh and roe
Beta-carotene - found in high concentrations in butternut squash, carrots, orange bell peppers, pumpkins, kale, peaches, apricots, mango, turnip greens, broccoli, spinach, and sweet potatoes
Canthaxanthin
Cryptoxanthin - present in papaya, egg yolk, butter, apples
Lutein - found in high concentration in spinach, kale, Swiss chard, collard greens, beet and mustard greens, endive, red pepper, and okra
Lycopene - found in high concentration in cooked red tomato products such as canned tomatoes, tomato sauce, tomato juice and garden cocktails, guava, and watermelons.
Zeaxanthin - best sources are kale, collard greens, spinach, turnip greens, Swiss chard, mustard and beet greens, corn, and broccoli
== Polyphenols ==
Natural phenols are a class of molecules found in abundance in plants. Many common foods contain rich sources of polyphenols that have antioxidant properties only in test tube studies. As interpreted by the Linus Pauling Institute, dietary polyphenols have little or no direct antioxidant food value following digestion. Not like controlled test tube conditions, the fate of flavones or polyphenols in vivo shows they are poorly absorbed and poorly conserved (less than 5%), so that most of what is absorbed exists as metabolites modified during digestion, destined for rapid excretion.
Spices, herbs, and essential oils are rich in polyphenols in the plant itself and shown with antioxidant potential in vitro. Red wine is high in total polyphenol count that supplies antioxidant quality that is unlikely to be conserved following digestion (see section below).
Deeply pigmented fruits such as cranberries, blueberries, plums, blackberries, raspberries, strawberries, blackcurrants, and other fruits such as figs, cherries, guava, oranges, mango, grape juice, and pomegranate juice also have significant polyphenol content.
Sorghum bran, cocoa powder, and cinnamon are rich sources of procyanidins, which are large molecular weight compounds found in many fruits and some vegetables. Partly due to the large molecular weight (size) of these compounds, their amount absorbed in the body is low, however, an effect also resulting from the action of stomach acids, enzymes, and bacteria in the gastrointestinal tract where smaller derivatives are metabolized and excreted.
=== Flavonoids ===
Flavonoids, a subset of polyphenol antioxidants, are present in many berries, as well as in coffee and tea.

This article lists several areas, regions, and municipalities that have either been completely or markedly depopulated, or are involved in plans for depopulation or relocation due to anthropogenic climate change. Several factors created or worsened by climate change can be responsible for necessitating managed retreat or the relocation of people and/or infrastructure. These include rising sea levels, increased flooding risk, changes to the makeup of the land (e.g. a habitable area becoming a wetland), coastal erosion, increased susceptibility to dangerous cyclones, droughts, water shortages, wildfires, and other factors, all of which can overlap with each other to enhance the risk of danger or inhabitability of a formerly populated region.
The lists contain a general number of the number of people moved or at risk of being moved due to climate change-related causes, as well as rough dates for when programs to relocate were first created or for when a climate disaster first caused significant forcible displacement of a population.

In organic chemistry the addition of the prefix benzo to the name of a chemical compound indicates the addition of an even number of carbon atoms to an unsaturated or already aromatic compound by which a new aromatic ring is formed. Between the prefix benzo and the name of the parent compound then place of the addition of the extra carbon atoms is indicated by letters written between square brackets. Quite often the number of added carbon atoms is four, although sometimes two else will do the job as shown in the following table. The first entry also shows different routes to the name of the same molecule.

Crystal structures of protein and nucleic acid molecules and their complexes are central to the practice of most parts of biophysics, and have shaped much of what we understand scientifically at the atomic-detail level of biology. Their importance is underlined by the United Nations declaring 2014 as the International Year of Crystallography, as the 100th anniversary of Max von Laue's 1914 Nobel Prize for discovering the diffraction of X-rays by crystals. This chronological list of biophysically notable protein and nucleic acid structures is loosely based on a review in the Biophysical Journal. The list includes all the first dozen distinct structures, those that broke new ground in subject or method, and those that became model systems for work in future biophysical areas of research.
== Myoglobin ==
1958 Myoglobin was the very first crystal structure of a protein molecule. Myoglobin cradles an iron-containing heme group that reversibly binds oxygen for use in powering muscle fibers, and those first crystals were of myoglobin from the sperm whale, whose muscles need copious oxygen storage for deep dives. The myoglobin 3-dimensional structure is made up of 8 alpha-helices, and the crystal structure showed that their conformation was right-handed and very closely matched the geometry proposed by Linus Pauling, with 3.6 residues per turn and backbone hydrogen bonds from the peptide NH of one residue to the peptide CO of residue i+4. Myoglobin is a model system for many types of biophysical studies, especially involving the binding process of small ligands such as oxygen and carbon monoxide.
== Hemoglobin ==
1960 The hemoglobin crystal structure showed a tetramer of two related chain types and was solved at much lower resolution than the monomeric myoglobin, but it clearly had the same basic 8-helix architecture (now called the "globin fold"). Further hemoglobin crystal structures at higher resolution (PDB 1MHB, 1DHB) soon showed the coupled change of both local and quaternary conformation between the oxy and deoxy states of hemoglobin, which explains the cooperativity of oxygen binding in the blood and the allosteric effect of factors such as pH and DPG. For decades hemoglobin was the primary teaching example for the concept of allostery, as well as being an intensive focus of research and discussion on allostery. In 1909, hemoglobin crystals from >100 species were used to relate taxonomy to molecular properties. That book was cited by Perutz in the 1938 report of horse hemoglobin crystals that began his long saga to solve the crystal structure. Hemoglobin crystals are pleochroic — dark red in two directions and pale red in the third — because of the orientation of the hemes, and the bright Soret band of the heme porphyrin groups is used in spectroscopic analysis of hemoglobin ligand binding.
== Hen-egg-white lysozyme ==
1965 Hen-egg-white lysozyme (PDB file 1lyz). was the first crystal structure of an enzyme (it cleaves small carbohydrates into simple sugars), used for early studies of enzyme mechanism. It contained beta sheet (antiparallel) as well as helices, and was also the first macromolecular structure to have its atomic coordinates refined (in real space). The starting material for preparation can be bought at the grocery store, and hen-egg lysozyme crystallizes very readily in many different space groups; it is the favorite test case for new crystallographic experiments and instruments. Recent examples are nanocrystals of lysozyme for free-electron laser data collection and microcrystals for micro electron diffraction.
== Ribonuclease ==
1967 Ribonuclease A (PDB file 2RSA) is an RNA-cleaving enzyme stabilized by 4 disulfide bonds. It was used in Anfinsen's seminal research on protein folding which led to the concept that a protein's 3-dimensional structure was determined by its amino-acid sequence. Ribonuclease S, the cleaved, two-component form studied by Fred Richards, was also enzymatically active, had a nearly identical crystal structure (PDB file 1RNS), and was shown to be catalytically active even in the crystal, helping dispel doubts about the relevance of protein crystal structures to biological function.
== Serine proteases ==
1967 The serine proteases are a historically very important group of enzyme structures, because collectively they illuminated catalytic mechanism (in their case, by the Ser-His-Asp "catalytic triad"), the basis of differing substrate specificities, and the activation mechanism by which a controlled enzymatic cleavage buries the new chain end to properly rearrange the active site. The early crystal structures included chymotrypsin (PDB file 2CHA), chymotrypsinogen (PDB file 1CHG), trypsin (PDB file 1PTN), and elastase (PDB file 1EST). They also were the first protein structures that showed two near-identical domains, presumably related by gene duplication. One reason for their wide use as textbook and classroom examples was the insertion-code numbering system, which made Ser195 and His57 consistent and memorable despite the protein-specific sequence differences.
== Papain ==
1968 Papain
== Carboxypeptidase ==
1969 Carboxypeptidase A is a zinc metalloprotease. Its crystal structure (PDB file 1CPA) showed the first parallel beta structure: a large, twisted, central sheet of 8 strands with the active-site Zn located at the C-terminal end of the middle strands and the sheet flanked on both sides with alpha helices. It is an exopeptidase that cleaves peptides or proteins from the carboxy-terminal end rather than internal to the sequence. Later a small protein inhibitor of carboxypeptidase was solved (PDB file 4CPA) that mechanically stops the catalysis by presenting its C-terminal end just sticking out from between a ring of disulfide bonds with tight structure behind it, preventing the enzyme from sucking in the chain past the first residue.
== Subtilisin ==
1969 Subtilisin (PDB file 1sbt ) was a second type of serine protease with a near-identical active site to the trypsin family of enzymes, but with a completely different overall fold. This gave the first view of convergent evolution at the atomic level. Later, an intensive mutational study on subtilisin documented the effects of all 19 other amino acids at each individual position.
== Lactate dehydrogenase ==
1970 Lactate dehydrogenase

== Trypsin inhibitor ==
1970 Basic pancreatic trypsin inhibitor, or BPTI (PDB file 2pti), is a small, very stable protein that has been a highly productive model system for study of super-tight binding, disulfide bond (SS) formation, protein folding, molecular stability by amino-acid mutations or hydrogen-deuterium exchange, and fast local dynamics by NMR. Biologically, BPTI binds and inhibits trypsin while stored in the pancreas, allowing activation of protein digestion only after trypsin is released into the stomach.
== Rubredoxin ==
1970 Rubredoxin (PDB file 2rxn) was the first redox structure solved, a minimalist protein with the iron bound by 4 Cys sidechains from 2 loops at the top of β hairpins. It diffracted to 1.2Å, enabling the first reciprocal-space refinement of a protein (4,5rxn). (NB: note that 4rxn was done without geometry restraints.) Archaeal rubredoxins account for many of the highest-resolution small structures in the PDB.
== Insulin ==
1971 Insulin (PDB file 1INS) is a hormone central to the metabolism of sugar and fat storage, and important in human diseases such as obesity and diabetes. It is biophysically notable for its Zn binding, its equilibrium between monomer, dimer, and hexamer states, its ability to form crystals in vivo, and its synthesis as a longer "pro" form which is then cleaved to fold up as the active 2-chain, SS-linked monomer. Insulin was a success of NASA's crystal-growth program on the Space Shuttle, producing bulk preparations of very uniform tiny crystals for controlled dosage.

The crystal structures (PDB files 2zuo, 2zv4, 2zv5 and 4hl8) show that each half of the vault is made up of 39 copies of a long 12-domain protein that swirl together to form the enclosure. Disorder at the very top and bottom ends suggests openings for possible access to the interior of the vault.

Carboxylic acids are organic acids characterized by a carboxyl (-COOH) functional group. The naming of these compounds is governed by IUPAC nomenclature, which ensures systematic and consistent naming of chemicals. Numerous organic compounds have other common names, often originating in historical source material thereof. The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid.
This list is ordered by the number of carbon atoms in a carboxylic acid.

Chemical classification systems attempt to classify elements or compounds according to certain chemical functional or structural properties. Whereas the structural properties are largely intrinsic, functional properties and the derived classifications depend to a certain degree on the type of chemical interaction partners on which the function is exerted. Sometimes other criteria like purely physical ones (e.g. molecular weight) or on the other hand functional properties above the chemical level are also used for building chemical taxonomies.
Some systems mix the various levels, resulting in hierarchies where the domains are slightly confused, for example having structural and functional aspects end up on the same level. Whereas chemical function is closely dependent on chemical structure, the situation becomes more involved when e.g. pharmacological function is integrated, because the QSAR can usually not be directly computed from structural qualities.

Cheminformatics toolkits are notable software development kits that allow cheminformaticians to develop custom computer applications for use in virtual screening, chemical database mining, and structure-activity studies. Toolkits are often used for experimentation with new methodologies. Their most important functions deal with the manipulation of chemical structures and comparisons between structures. Programmatic access is provided to properties of individual bonds and atoms.
== Functionality ==
Toolkits provide the following functionality:
Read and save structures in various chemistry file formats.
Determine if one structure is a substructure of another (substructure matching).
Determine if two structures are equal (exact matching).
Identification of substructures common to structures in a set (maximal common substructure, MCS).
Disassemble molecules, splitting into fragments.
Assemble molecules from elements or submolecules.
Apply reactions on input reactant structures, resulting in output of reaction product structures.
Generate molecular fingerprints. Fingerprints are bit-vectors where individual bits correspond to the presence or absence of structural features. The most important use of fingerprints is in indexing of chemistry databases.

== Reactions and ions ==
=== Redox reactions ===
A redox reaction is a chemical reaction in which there is a change in oxidation state of atoms participating in the reaction.
=== Ions ===
An atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called a reducing agent). It is accomplished by loss of one or more electrons. The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced. This relation can be remembered by the following mnemonics.
Leo says Ger! or Leo the lion, Ger! can be used to represent Loss of electron is oxidation; Gain of electron is reduction.
Oil Rig: Oxidation is loss; Reduction is gain (of electrons).
Cations are Plussy Cats.
=== Cations and anions ===
Cations are positively (+) charged ions while anions are negatively () charged. This can be remembered with the help of the following mnemonics.
Cats have paws ⇔ Cations are pawsitive.
Ca+ion: The letter t in cation looks like a + (plus) sign.
An anion is a negative ion. (Anegativeion ⇒ Anion).
=== Oxidation vs. reduction: electrochemical cell and electron gain/loss ===
AN OIL RIG CAT:
At the ANode, Oxidation Involves Loss of electrons.
Reduction Involves Gaining electrons at the CAThode.
LOAN Left Anode Oxidation Negative.
In written representation of galvanic cell, anode is written on the left. It is the electrode where oxidation takes place. It is the negative electrode. Obviously, the opposite properties (Right/Cathode/Reduction/Positive) are found on the cathode. Hence, by remembering LOAN mnemonic, we can arrive at the corresponding properties for the cathode.
LEO the lion says GER [grr]:
"Loss of Electrons, Oxidation; Gain of Electrons, Reduction".
=== Electrodes ===
An electrode in which oxidation takes place is called an anode while in that which reduction takes place is called cathode. This applies for both electrolytic and electrochemical cells, though the charge on them reverses. The red cat and an ox mnemonics are useful to remember the same.
Red cat: Reduction at cathode
An ox: Anode for oxidation.
PANIC: Positive Anode, Negative Is Cathode
The words oxidation and anode, both begin with vowels.
Also, both reduction and cathode begin with consonants.
Fat Cat: electrons flow From Anode To Cathode
LOAN: Left side;Oxidation;Anode;Negative.
ACID: Anode Current Into Device
== Compounds ==
=== Diatomic molecules ===
Molecules exhibiting diatomic structures can be remembered through the following mnemonics.
Have No Fear Of Ice Cold Beer.
Horses Need Oats For Clear Brown Eyes (I's).
Her Nana's Only Functioning Clicker Broke Instantly.
BrINClHOF: say Brinkelhof.
I Bring Clay For Our New House.
CHINFOB
HONClBrIF say honk-le-brif
Captain HOFBrINCl says "Don't forget diatomic elements!"
HONey it's the Halogens (Hydrogen, Oxygen, Nitrogen, plus the Halogens)
=== Hydrogen bonds ===
Hydrogen forms hydrogen bonds with three elements which are nitrogen (N), oxygen (O) and fluorine (F). The names of these elements can be remembered by the following mnemonic.
Hydrogen is FON! (fun).
Hydrogen likes to have FON!
=== Polyatomic ions: -ate and -ite ions ===
Super Popeye Constantly Clubbed Brutus In Nevada.
Nick Brit the Camel ate an Inky Clam with Crêpes for Supper in Phoenix.
Number of consonants denotes number of oxygen atoms. Number of vowels denotes negative charge quantity. Inclusion of the word "ate" signifies that each ends with the letters a-t-e. To use this for the -ite ions, simply subtract one oxygen but keep the charge the same.
== Organic chemistry ==
=== Prefixes for naming carbon chains ===
The prefixes for naming carbon chains containing one to four carbons. For chains containing five or more carbons, the inorganic prefixes (e.g. pent = 5, hept = 7) are used.
Monkeys Eat Peeled Bananas
Most Elephants Poop Bananas
For the first five chains.
Many Elephants Pee Behind Plants
Mom Eats Pretty Big Pears
=== Carboxylic acids ===
Common names of homogeneous aliphatic carboxylic acids:
Frogs Are Polite, Being Very Courteous.
=== Dicarboxylic acids ===
The sequence of dicarboxylic acids can be remembered with following mnemonics.
Oh My, Such Good Apples.
Oh My Stars, Green Apples.
Oh My, Such Good Apple Pie, Sweet As Sugar.
Oh My Stars, Go Ahead Please
OMSGAPS is a phonetic word for the first letters of the first seven dicarboxylic acids above in sequence can be said as below.

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color. Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III). These salts (mostly the (II) salts) are often blue to green in color, rather than the orange color copper is known for. Despite being considered a semi-noble metal, copper is one of the most common salt-forming transition metals, along with iron.

This is a list of sovereign states and territories by carbon dioxide emissions due to certain forms of human activity, based on the EDGAR database created by the European Commission and Netherlands Environmental Assessment Agency. The following table lists the annual CO2 emissions estimates (in kilotons of CO2 per year) for the year 2023, as well as the change from the year 2000.
The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use, land-use change and forestry. Over the last 150 years, estimated cumulative emissions from land use and land-use change represent approximately one-third of total cumulative anthropogenic CO2 emissions. Emissions from international shipping or bunker fuels are also not included in national figures, which can make a large difference for small countries with important ports.
In 2023, global GHG emissions reached 53.0 GtCO2eq (without Land Use, land Use Change and Forestry). The 2023 data represent the highest level recorded and experienced an increase of 1.9% or 994 MtCO2eq compared to the levels in 2022. The majority of GHG emissions consisted of fossil CO2 accounting for 73.7% of total emissions.
China, the United States, India, the European Union, Russia and Brazil were the world's largest GHG emitters in 2023. Together they account for 49.8% of global population, 63.2% of global gross domestic product, 64.2% of global fossil fuel consumption and 62.7% of global GHG emissions. Among these top emitters, in 2023 China, India, Russia and Brazil increased their emissions compared to 2022, with India having the largest increase in relative terms (+ 6.1%) and China the largest absolute increase by 784 MtCO2eq.
CO2 emissions from the top 10 countries with the highest emissions accounted for almost two thirds of the global total. Since 2006, China has been emitting more CO2 than any other country. However, the main disadvantage of measuring total national emissions is that it does not take population size into account. China has the largest CO2 emissions in the world, but also the second largest population. Some argue that for a fair comparison, emissions should be analyzed in terms of the amount of CO2 per capita. Their main argument is illustrated by CO2 per capita emissions in 2023, China's levels (9.24) are almost two thirds those of the United States (13.83) and less than a sixth of those of Palau (62.59 the country with the highest emissions of CO2 per capita).
Measures of territorial-based emissions, also known as production-based emissions, do not account for emissions embedded in global trade, where emissions may be imported or exported in the form of traded goods, as it only reports emissions emitted within geographical boundaries. Accordingly, a proportion of the CO2 produced and reported in Asia and Africa is for the production of goods consumed in Europe and North America.
Greenhouse gases (GHG) primarily carbon dioxide but also others, including methane and chlorofluorocarbons trap heat in the atmosphere, leading to global warming. Higher temperatures then act on the climate, with varying effects. For example, dry regions might become drier while, at the poles, the ice caps are melting, causing higher sea levels. In 2016, the global average temperature was already 1.1°C above pre-industrial levels.
According to the review of the scientific literature conducted by the Intergovernmental Panel on Climate Change (IPCC), carbon dioxide is the most important anthropogenic greenhouse gas by warming contribution. The other major anthropogenic greenhouse gases) are not included in the following list, nor are humans emissions of water vapor (H2O), the most important greenhouse gases, as they are negligible compared to naturally occurring quantities. Space-based measurements of carbon dioxide should allow independent monitoring in the mid-2020s.

This is a list of substances or materials generally considered discredited.
A substance can be discredited in one of three ways:
It was widely believed to exist at one time but no longer is. Such substances are often part of an obsolete scientific theory.
It was once believed to have drastically different properties from those accepted now. It was widely claimed and believed to possess significant properties that are no longer attributed to it.
It is currently believed to exist as part of a theory that has not met the theoretical and experimental requirements of mainstream science. In particular, such a theory must be predictive.
== Substances whose existence is discredited ==
== Substances whose properties are discredited ==
This is not to be construed as implying that these itemsas they are understood todayare discredited. What is listed are fire, water, metal, etc. as universal principles or fundamentals.
Classical elements and Chinese elements discredited by atomic theory and nuclear physics.
Fire (classical element)
Water (classical element)
Earth (classical element)
Air (classical element)
Wood (classical element)
Metal (classical element)
Aether (classical element): Now known not to exist (see above)
The four bodily humours: Blood, Phlegm, Black Bile, and Yellow Bile. Fluids believed to determine health and character. Discredited by modern biology, including discovery of hormones.
The tria prima of Paracelsus and later alchemy: Salt, Mercury and Sulphur. Discredited by modern chemistry (the atomic theory and modern understanding of elements and compounds).
