MeSH

structure in first source

Date introduced: September 25, 2002

A class of compounds named after and generally derived from C20 fatty acids (EICOSANOIC ACIDS) that includes PROSTAGLANDINS; LEUKOTRIENES; THROMBOXANES, and HYDROXYEICOSATETRAENOIC ACIDS. They have hormone-like effects mediated by specialized receptors (RECEPTORS, EICOSANOID).

Year introduced: 1990

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 in which the carbon chain contains one or more double or triple carbon-carbon bonds.

Year introduced: 1973

Long chain organic acid molecules that must be obtained from the diet. Examples are LINOLEIC ACIDS and LINOLENIC 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: 1975

Amino acids and chains of amino acids connected by peptide linkages.

Year introduced: 1998

Organic compounds that generally contain an amino (-NH2) and a carboxyl (-COOH) group. Twenty alpha-amino acids are the subunits which are polymerized to form proteins.
