MSH: 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 & Hackh's Chemical Dictionary, 5th ed),CSP: organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid; chemically R COOH where R is an aliphatic moiety; the common fatty acids of biological origin are linear chains with an even number of carbon atoms.,CHV: a major component of fats,CHV: a major component of fats,NCI: A major component of fats that are used by the body for energy and tissue development.,NCI: Monobasic, aliphatic acids with varying chain lengths between 6 and 30. Fatty acids are a major constituent in all fats and can be either saturated, monounsaturated, or polyunsaturated. Saturated and monounsaturated fatty acids are synthesized by the body, whereas polyunsaturated fatty acids are not and must
