Glutathione oxidized (L-Glutathione oxidized)

Glutathione oxidized (L-Glutathione oxidized), an oxidized form of the antioxidant L-glutathione, acts as a signaling molecule that trigger the activation of antioxidant genes ^[1]. Glutathione oxidized can be reduced to GSH under the action of glutathione reductase in the presence of NADPH for cellular antioxidant defense ^[2]. Glutathione oxidized is a biomarker of oxidative stress status and can be used to evaluate oxidative stress may be involved in various diseases^[3].

Glutathione oxidized (L-Glutathione oxidized)，是抗氧化剂L-谷胱甘肽的氧化形式，作为一种信号分子，可触发抗氧化基因的激活^[1]。在NADPH存在下，Glutathione oxidized可在谷胱甘肽还原酶的作用下被还原为GSH，以实现细胞的抗氧化防御^[2]。Glutathione oxidized是氧化应激状态的生物标志物，可用于评估氧化应激可能参与的各种疾病^[3]。
