What is the origin of the word "linolenic"?
The word linolenic is an irregular derivation from linoleic, which itself is derived from the Greek word linon ( flax ). Oleic means "of or relating to oleic acid " because saturating linoleic acid's omega-6 double bond produces oleic acid.
When was linolenic acid first synthesized?
Bedford of the University of Halle an der Saale, Germany, and by Adolf Rollett of the Universität Berlin, Germany, working independently, as cited in J. W. McCutcheon's synthesis in 1942, and referred to in Green and Hilditch's 1930s survey. It was first artificially synthesized in 1995 from C6 homologating agents. A Wittig reaction of the phosphonium salt of [ ( Z-Z )-nona-3,6-dien-1-yl]triphenylphosphonium bromide with methyl 9-oxononanoate, followed by saponification, completed the synthesis.

In terms of its structure, it is named all - cis -9,12,15-octadecatrienoic acid. In physiological literature, it is listed by its lipid number, 18:3 , and ( n −3). It is a carboxylic acid with an 18-carbon chain and three cis double bonds. The first double bond is located at the third carbon from the methyl end of the fatty acid chain, known as the n end. Thus, α-linolenic acid is a polyunsaturated n −3 (omega-3) fatty acid. It is an isomer of gamma-linolenic acid (GLA), an 18:3 ( n −6) fatty acid (i.e., a polyunsaturated omega-6 fatty acid with three double bonds).

Overview
alpha-Linolenic acid (ALA), also known as α-Linolenic acid (from Greek alpha meaning "first" and linon meaning flax), is an n−3, or omega-3, essential fatty acid. ALA is found in many seeds and oils, including flaxseed, walnuts, chia, hemp, and many common vegetable oils.
In terms of its structure, it is named all-cis-9,12,15-octadecatrienoic acid. In phy…
Potential role in nutrition and health
Although the best source of ALA is seeds, most seeds and seed oils are much richer in an n−6 fatty acid, linoleic acid. Exceptions include flaxseed (must be ground for proper nutrient absorption) and chia seeds. Linoleic acid is the other essential fatty acid, but it, and the other n−6 fatty acids, compete with n−3s for positions in cell membranes and have very different effects on human health. There is a complex set of essential fatty acid interactions.
Etymology
The word linolenic is an irregular derivation from linoleic, which itself is derived from the Greek word linon (flax). Oleic means "of or relating to oleic acid" because saturating linoleic acid's omega-6 double bond produces oleic acid.
Dietary sources
Seed oils are the richest sources of α-linolenic acid, notably those of hempseed, chia, perilla, flaxseed (linseed oil), rapeseed (canola), and soybeans. α-Linolenic acid is also obtained from the thylakoid membranes in the leaves of Pisum sativum (pea leaves). Plant chloroplasts consisting of more than 95 percent of photosynthetic thylakoid membranes are highly fluid due to the large abundance of linolenic acid, that shows up as sharp resonances in high-resolution carbon-13 N…
History
In 1887, linolenic acid was discovered and named by the Austrian chemist Karl Hazura of the Imperial Technical Institute at Vienna (although he didn't separate its optical isomers). α-Linolenic acid was first isolated in pure form in 1909 by Ernst Erdmann and F. Bedford of the University of Halle an der Saale, Germany, and by Adolf Rollett of the Universität Berlin, Germany, working independently, as cited in J. W. McCutcheon's synthesis in 1942, and referred to in Green and H…
