OriginDerived from plant oils such as soybean, flaxseed, or canola through extraction and purification processes. Produced synthetically via catalytic hydrogenation or chemical synthesis from linoleic acid or other polyunsaturated fatty acid precursors.
Alpha-linolenic acid is a linolenic acid with cis-double bonds at positions 9, 12 and 15. Shown to have an antithrombotic effect. It has a role as a micronutrient, a nutraceutical and a mouse metabolite. It is a linolenic acid and an omega-3 fatty acid. It is a conjugate acid of an alpha-linolenate and a (9Z,12Z,15Z)-octadeca-9,12,15-trienoate.
