Description(R)-lipoic 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 (R)-lipoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (R)-lipoic acid exists in all living species, ranging from bacteria to humans.

Enzymes

General function:
Involved in catalytic activity
Specific function:
Catalyzes both the ATP-dependent activation of exogenously supplied lipoate to lipoyl-AMP and the transfer of the activated lipoyl onto the lipoyl domains of lipoate-dependent enzymes
Gene Name:
AIM22
