Glutathione (r-glutamyl cysteingl + glycine, GSH) is a tripeptide containing γ-amide bonds and sulfhydryl groups, composed of glutamic acid, cysteine, and glycine, and is found in almost every cell of the body [1]. Glutathione helps maintain normal immune system function and has antioxidant and integrative detoxification effects [1]. The sulfhydryl group on cysteine is its active group (often abbreviated as G-SH), which can easily bind to certain drugs and toxins, making it have an integrated detoxification effect [2]. Glutathione can not only be used in drugs, but also as a base material for functional foods, and is widely used in functional foods such as anti-aging, enhancing immunity, and anti-tumor. [2] There are two forms of glutathione: reduced (G-SH) and oxidized (G-S-S-G), and reduced glutathione accounts for the vast majority under physiological conditions. Glutathione reductase catalyzes the interchange between the two types, and the enzyme's coenzyme also provides NADPH for pentose phosphate bypass metabolism
