11,12-dihydroxy-5,8,14-eicosatrienoic acid [Supplementary Concept]
arachidonic acid metabolite in rabbit renal cortex
Date introduced: November 4, 1981
Eicosanoids
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
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.

Fatty Acids, Unsaturated
FATTY ACIDS in which the carbon chain contains one or more double or triple carbon-carbon bonds.
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)
