GW9508 [Supplementary Concept]
structure in first source
Date introduced: December 20, 2006
Propionates
Derivatives of propionic acid. Included under this heading are a broad variety of acid forms, salts, esters, and amides that contain the carboxyethane structure.
Year introduced: 1966
Organic Chemicals
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.
Year introduced: 1998
Methylamines
Derivatives of methylamine (the structural formula CH3NH2).
Year introduced: 1973(1971)
Lipids
A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids. (Grant and Hackh's Chemical Dictionary, 5th ed)
Year introduced: /blood was BLOOD LIPIDS 1963-1967
Fatty Acids, Volatile
Short-chain fatty acids of up to six carbon atoms in length. They are the major end products of microbial fermentation in the ruminant digestive tract and have also been implicated in the causation of neurological diseases in humans.
Year introduced: 1973
Fatty Acids
Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED). (Grant and Hackh's Chemical Dictionary, 5th ed)
Year introduced: /metabolism was FATTY ACID METABOLISM 1965
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.
Amines
A group of compounds derived from ammonia by substituting organic radicals for the hydrogens. (From Grant and Hackh's Chemical Dictionary, 5th ed)
Acids, Acyclic
Carboxylic acids that have open-chain molecular structures as opposed to ring-shaped structures.
