용도
개요
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.
용도
(±)-α-Lipoic acid has been used in in vitro lipoylation studies and in the pyruvate dehydrogenase complex (PDC)-pyruvate dehydrogenase kinase (PDHK) functional assay. It has also been used to investigate its antioxidative effect on developing cerebellum of rats exposed to arsenic during postnatal period.
일반 설명
Oxidized form. Has antioxidant properties. Growth factor for many bacteria and protozoa.
