Encyclopedic overview
Arachidic acid, also known as icosanoic acid, is a saturated fatty acid with a 20-carbon chain. It is a minor constituent of cupuaçu butter (7%), perilla oil (0–1%), peanut oil (1.1–1.7%), corn oil (3%), and cocoa butter (1%). The salts and esters of arachidic acid are known as arachidates.
Its name derives from the Latin arachis—peanut. It can be formed by the hydrogenation of arachidonic acid.
