Etymology: translating German linolensäure (K. Hazura 1887, in Sitzungsber. d. K. Akad. d. Wissensch. (Math.-Nat. Classe) XCV. ii. 1055), < linolsäure linoleic adj. acid with insertion of -en -ene comb. form.

Chemistry.

A liquid unsaturated carboxylic acid, C₁₈H₃₀O₂, which is found as a glyceride in linseed and most other drying oils: 9,12,15-octadecatrienoic acid.

1887 Jrnl. Chem. Soc. 52 913 The acids from drying oils contain both linolic acid, C₁₈H₃₂O₂, and linolenic acid, C₁₈H₃₀O₂.

1921 Jrnl. Chem. Soc. 119 1307 The product of the action of zinc on linolenic acid hexabromide was a mixture of α- and β-linolenic acids, although only the α-modification occurs naturally.

1951 R. Mayer Artist's Handbk. (new ed.) iii. 111 Poppy oil..owes its property of yellowing less than linseed oil to the smaller percentage of linolenic acid it contains.

1969 J. I. Routh et al. Essent. Gen., Org. & Biochem. xxxiii. 643 Unsaturated fatty acids such as linoleic and linolenic are essential components of cellular lipids that must be obtained in the diet, since they cannot be synthesized by the body.
