Metabolite Identification
Common NameMethyl Arachidonate
DescriptionMethyl Arachidonate, also known as Arachidonate methyl ester or (5Z,8Z,11Z,14Z)-Icosatetraenoate methyl ester, is classified as a member of the Fatty acid methyl esters. Fatty acid methyl esters are compounds containing a fatty acid that is esterified with a methyl group. They have the general structure RC(=O)OR', where R=fatty aliphatic tail or organyl group and R'=methyl group. Methyl Arachidonate is considered to be practically insoluble (in water) and basic. Methyl Arachidonate can be synthesized from arachidonic acid. Methyl Arachidonate can be synthesized into 12(R)-HPETE methyl ester and 12(S)-HPETE methyl ester
