Natural Product Identification
Common NameArachidic acid
DescriptionArachidic acid, also known as icosanoic acid, is a saturated fatty acid with a 20-carbon chain. It is a minor constituent of butter, perilla oil, peanut oil, corn oil, and cocoa butter. It also constitutes 7.08% Of the fats from the fruit of the durian species Durio graveolens. The salts and esters of arachidic acid are known as arachidates. Its name derives from the Latin arachis that means peanut. It can be formed by the hydrogenation of arachidonic acid. The reduction of arachidic acid yields arachidyl alcohol. Arachidic acid is used for the production of detergents, photographic materials and lubricants. Arachidic acid belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Arachidic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral.
