GSH是由谷氨酸、半胱氨酸和甘氨酸组成的含巯基的三肽,广泛存在于生物体内。它参与维持细胞的正常氧化还原状态。对于需要巯基的酶有保护与恢复活性的功能,从而促进糖、脂肪与蛋白质代谢。它是多种酶的辅基与辅酶,参与三羧酸循环与糖代谢,使机体获得能量。谷胱甘肽过氧化酶 GSH is a thiol-containing tripeptide composed of glutamic acid, cysteine ​​and glycine and is widely present in the body. It is involved in maintaining the normal redox state of the cell. For thiol-dependent enzymes have the ability to protect and restore activity, thereby promoting sugar, fat and protein metabolism. It is a variety of enzyme cofactor and coenzyme, involved in the cycle of tricarboxylic acid and glucose metabolism, so that the body to gain energy. Glutathione peroxidase
