Metabolite Identification
Common Name12-Hydroxystearic acid
Description12-Hydroxystearic acid, also known as 12-hydroxy-octadecanoate or DL-12-hydroxy stearate, 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. 12-Hydroxystearic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
