Metabolite Identification
Common NamePaullinic acid
DescriptionPaullinic acid, also known as C20:1N-7 or (Z)-13-icosenoate, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Paullinic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
