Organic Chemicals
Medical Definition: | A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form. |
Guide Notes: | GEN or unspecified; prefer specific groups or specific chemicals |
Alcohols - Alkyl compounds containing a hydroxyl group. They are classified according to relation of the carbon atom: primary alcohols, R-CH2OH; secondary alcohols, R2-CHOH; tertiary alcohols, R3-COH. (From Grant & Hackh's Chemical Dictionary, 5th ed) | |
Aldehydes - Organic compounds containing a carbonyl group in the form -CHO. | |
Amides - Organic compounds containing the -CO-NH2 radical. Amides are derived from acids by replacement of -OH by -NH2 or from ammonia by the replacement of H by an acyl group. (From Grant & Hackh's Chemical Dictionary, 5th ed) | |
Amidines | |
Amines - A group of compounds derived from ammonia by substituting organic radicals for the hydrogens. (From Grant & Hackh's Chemical Dictionary, 5th ed) | |
Anhydrides - Chemical compounds derived from acids by the elimination of a molecule of water. | |
Aza Compounds | |
Azo Compounds | |
Carboxylic Acids - Organic compounds containing the carboxy group (-COOH). This group of compounds includes amino acids and fatty acids. Carboxylic acids can be saturated, unsaturated, or aromatic. | |
Catenanes - Complex compounds where two cyclic molecules are interlaced together as links in a chain. They have potential use in NANOTECHNOLOGY. | |
Cyanates - Organic salts of cyanic acid containing the -OCN radical. | |
Ethers | |
Glycosylation End Products, Advanced - Products derived from the nonenzymatic reaction of glucose and proteins in vivo that exhibit a yellow-brown pigmentation and an ability to participate in protein-protein cross-linking. These substances are involved in biological processes relating to protein turnover and it is believed that their excessive accumulation contributes to the chronic complications of diabetes mellitus. | |
Hydrazines | |
Hydrocarbons | |
Imides | |
Imines | |
Isocyanates - Organic compounds that contain the -NCO radical. | |
Ketones | |
Lactones | |
Nitriles - Organic compounds containing the -CN radical. The concept is distinguished from CYANIDES, which denotes inorganic salts of HYDROGEN CYANIDE. | |
Nitro Compounds | |
Nitroso Compounds | |
Onium Compounds - Ions with the suffix -onium, indicating cations with coordination number 4 of the type RxA+ which are analogous to AMMONIUM COMPOUNDS (H4N+). Ions include phosphonium R4P+, oxonium R3O+, sulfonium R3S+, chloronium R2Cl+ | |
Organometallic Compounds - A class of compounds of the type R-M, where a C atom is joined directly to any other element except H, C, N, O, F, Cl, Br, I, or At. (Grant & Hackh's Chemical Dictionary, 5th ed) | |
Organophosphorus Compounds - Organic compounds that contain phosphorus as an integral part of the molecule. | |
Organoselenium Compounds - Organic compounds which contain selenium as an integral part of the molecule. | |
Organosilicon Compounds - Organic compounds that contain silicon as an integral part of the molecule. | |
Organothiophosphorus Compounds - Compounds containing carbon-phosphorus bonds in which the phosphorus component is also bonded to one or more sulfur atoms. Many of these compounds function as pesticides (e.g., INSECTICIDES, ORGANOTHIOPHOSPHATE). | |
Phenols | |
Quinones - Hydrocarbon rings which contain two ketone moieties in any position. They can be substituted in any position except at the ketone groups. | |
Rotaxanes - Complex compounds in which a dumbbell shaped molecule is encircled by a macrocycle. They are named after rota (wheel) and axis (axle). Notation with a prefix is used to indicate the number of interlocked components. They have potential use in NANOTECHNOLOGY. Rotaxanes have been made with CYCLODEXTRINS and CYCLIC ETHERS. | |
Semicarbazides | |
Triazenes | |
Urea - A compound formed in the liver from ammonia produced by the deamination of amino acids. It is the principal end product of protein catabolism and constitutes about one half of the total urinary solids. |
