linolenic acid

[¦lin·ə¦lin·ik ′as·əd]
(biochemistry)
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.

Among the improvements made possible by both a high oleic sunflower oil and a soybean oil with low linolenic and/or low linolenic coupled with high oleic acid are a clean label, improved diet, less oxidation potential, and increased frying stability due to the reduced level of highly unsaturated fatty acids and an increase in the level of monounsaturated fats without the need for further processing.
