Metabolite Identification
Common NameN-Oleoyl GABA
DescriptionN-oleoyl gaba belongs to the class of organic compounds known as gamma amino acids and derivatives. These are amino acids having a (-NH2) group attached to the gamma carbon atom. Thus, N-oleoyl gaba is considered to be a fatty amide lipid molecule. N-oleoyl gaba is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
