Metabolite Identification
Common NameLinoleoyl ethanolamide
DescriptionLinoleoyl ethanolamide, also known as linoleamide mea or anandamide (18:2, N-6), belongs to the class of organic compounds known as n-acylethanolamines. N-acylethanolamines are compounds containing an N-acyethanolamine moiety, which is characterized by an acyl group is linked to the nitrogen atom of ethanolamine. Thus, linoleoyl ethanolamide is considered to be a fatty amide. Based on a literature review very few articles have been published on Linoleoyl ethanolamide.
