Chemical structures of lipoic acid and lipoyllysine residue The figure illustrates the chemical structures of lipoic acid in its oxidized and reduced forms, its two enantiomers ( R - and S -lipoic acid), and its covalent attachment to a lysine residue of the E2 component of the -ketoacid dehydrogenase complex (and the H protein of the glycine cleavage system), forming a lipoyllysine moiety
