Metabolite Identification
Common Name2-Hydroxystearic acid
Description2-Hydroxystearic acid (CAS: 629-22-1), also known as 2-hydroxystearate or 2-hydroxyoctadecanoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. The chain of 2-hydroxystearic acid bears a hydroxyl group. 2-Hydroxystearic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 2-Hydroxystearic acid can be found in feces. 2-Hydroxystearic acid can be synthesized from octadecanoic acid, and can be synthesized into 2-hydroxystearoyl-CoA and N-2-hydroxystearoylsphingosine.
