MeSH

urinary metabolite of vinyl chloride; RN given refers to parent cpd; structure

Date introduced: January 1, 1969

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

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

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

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

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.

Year introduced: 1973(1971)

Carboxylic acids that have open-chain molecular structures as opposed to ring-shaped structures.

Year introduced: 1998

Derivatives of ACETIC ACID. Included under this heading are a broad variety of acid forms, salts, esters, and amides that contain the carboxymethane structure.

Year introduced: 1966
