Description and Uses

DL-α-Lipoic acid is a cyclic disulfide antioxidant that interconverts with its reduced dithiol form. It is an essential cofactor for decarboxylation reactions of the citric acid cycle, and acts as a general antioxidant. DL-α-lipoic acid can act as a direct radical scavenger, as a cofactor to regenerate reduced glutathione, and as a metal chelator.

Lipoic acid [CAS: 1077-28-7] (6,8-dimercaptooctanoic acid), a lipophilic endogenous disulfide that can be reduced to the dithiol dihydrolipoic acid, protects against free-radical-mediated injury both in vivo and in vitro.
