The chemical formula of DL-Thioctic acid is C8H14O2S2 which containing 8 Carbon atoms,14 Hydrogen atoms,2 Oxygen atoms and 2 Sulfur atoms,and the molecular weight of DL-Thioctic acid is 206.32.
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.
