Metabolite Identification
Common NameLipoic acid
DescriptionLipoic acid, also known as RLA or a-lipoate, belongs to the class of organic compounds known as lipoic acids and derivatives. Lipoic acids and derivatives are compounds containing a lipoic acid moiety (or a derivative thereof), which consists of a pentanoic acid (or derivative) attached to the C3 carbon atom of a 1,2-dithiolane ring. Lipoic acid is a drug which is used for nutritional supplementation, also for treating dietary shortage or imbalance. Lipoic acid exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Lipoic acid exists in all living species, ranging from bacteria to humans. In cattle, lipoic acid is involved in the metabolic pathway called the glycine and serine metabolism pathway.
