| saturated fatty acid | A fatty acid, the carbon chain of which contains no ethylenic or other unsaturated linkages between carbon atoms (e.g., stearic acid and palmitic acid); called saturated because it is incapable of absorbing any more hydrogen. (05 Mar 2000) |

| diethenoid fatty acid | A fatty acid containing two double bonds, e.g., linoleic acid. (05 Mar 2000) |
| omega-3 fatty acid desaturase | <enzyme> Catalyses desaturation of the omega-3 carbon (3rd from free end) of c-18 fatty acids; deficiency results in accumulation of linoleic acid (18:2omega6,9) at the expense of linolenic acid (18:3omega3,6,9); amino acid sequence given in first source Registry number: EC 1.14.99.- Synonym: fad3 gene product, omega-3 desaturase (26 Jun 1999) |
| essential fatty acid | <biochemistry> The three fatty acids required for growth in mammals, arachidonic, linolenic and linoleic acids. Only linoleic acid needs to be supplied in the diet, the other two can be made from it. (18 Nov 1997) |
| fatty | Containing fat, or having the qualities of fat; greasy; gross; as, a fatty substance. <medicine> Fatty acid, a tumour consisting of fatty or adipose tissue; lipoma. Source: Websters Dictionary (01 Mar 1998) |
| fatty acid | <biochemistry> Any number of saturated aliphatic monocarboxylic acids. A metabolic byproduct from the breakdown of fats. 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. Free fatty acids are present in living tissues at low concentrations. The esterified forms are important both as energy storage molecules and structural molecules. See: triglycerides, phospholipids. (15 Nov 1997) |
