C17H29COOH One of the principal unsaturated fatty acids in plants and an essential fatty acid in animal nutrition; a colorless liquid that boils at 230°C (17 mmHg or 2266 pascals), soluble in many organic solvents; used in medicine and drying oils. Also known as 9,12,15-octadecatrienoic acid.

Linolenic Acid


a monobasic carboxylic acid with three isolated double bonds, CH3(CH2CH=CH)3(CH2)7COOH; a colorless oily liquid. Boiling point, 184°C (at 532 newtons per sq m, or 4 mm of mercury); density, 0.905 g/cm3 at 20°C. Linolenic acid belongs to the category of irreplaceable fatty acids; it exists in triglyceride form in many vegetable oils—for example, linseed (up to 30 percent), perilla (up to 55 percent), hemp, and soy.
