Metabolite Identification
Common NameIsopalmitic acid
DescriptionIsopalmitic acid, also known as isopalmitate, 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. Isopalmitic acid exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule.
