Metabolite Identification
Common Name2(R)-hydroxydocosanoic acid
Description2(R)-hydroxydocosanoic acid, also known as a-hydroxybehenate or a-hydroxydocosanoate, belongs to the class of organic compounds known as very long-chain fatty acids. These are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. 2(R)-hydroxydocosanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
