Common Namealpha-Lipoic acid amide
ClassSmall Molecule
DescriptionLipoamidee, also known as lipoamidee or lipoamidee, belongs to the class of organic compounds known as lipoamidees. Lipoamidees are compounds containing a lipoamidee moiety, which consists of a pentanamide attached to the C3 carbon atom of a 1,2-dithiolane ring. Thus, lipoamidee is considered to be a fatty amide lipid molecule. Lipoamidee exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Lipoamidee exists in all living species, ranging from bacteria to humans. In cattle, lipoamidee is involved in the metabolic pathway called the citric Acid cycle pathway.
