Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 cis-9, and a main product of Δ9-desaturase.[2] It has the formula CH3−(CH2)7−CH=CH−(CH2)7−COOH.[3][page needed] The name derives from the Latin word oleum, which means oil.[4] It is the most common fatty acid in nature.[5] The salts and esters of oleic acid are called oleates. It is a common component of oils, and thus occurs in many types of food, as well as in soap.
