cis13docosenoic
Cis13docosenoic acid is a monounsaturated fatty acid with the chemical formula C22H42O2. It is a cis isomer of docosenoic acid, meaning the hydrogen atoms on the double bond are on the same side. The "13" indicates that the double bond is located between the 13th and 14th carbon atoms of the fatty acid chain, counting from the carboxyl group. This fatty acid is a type of omega-9 fatty acid, as the double bond is nine carbons away from the methyl end of the chain. Cis13docosenoic acid is a component of some natural fats and oils, although it is not as commonly found or studied as other more prevalent fatty acids like oleic acid or erucic acid. Its presence in biological systems is relatively minor. Research into specific biological functions or significant dietary roles for cis13docosenoic acid is limited compared to other fatty acids. Its chemical properties are characteristic of long-chain monounsaturated fatty acids, including a relatively low melting point due to the kink introduced by the cis double bond.
