L-Glutathione reduced (GSH; γ-L-Glutamyl-L-cysteinyl-glycine) is an endogenous antioxidant and is capable of scavenging oxygen-derived free radicals.
L-Glutathione reduced is a non-protein thiol widely exists in living cells. L-Glutathione reduced plays important biological functions in the organism, including protein and DNA synthesis, enzyme activity, metabolism and cell protection. L-Glutathione reduced is capable of scavenging oxygen-derived free radicals and is established to be a marker of oxidative stress[1].
L-谷胱甘肽还原（GSH；γ-L-谷氨酰-L-半胱氨酸-甘氨酸）是一种内源性抗氧化剂，能够清除氧衍生的自由基。
L-谷胱甘肽还原是一种广泛存在于活细胞中的非蛋白质硫醇。L-谷胱甘肽在生物体内具有重要的生物学功能，包括蛋白质和DNA的合成、酶活性、代谢和细胞保护。L-谷胱甘肽还原能够清除氧衍生的自由基，并被确定为氧化应激的标志物[1]。
