Glutathione disulfide - Wikipedia
Glutathione disulfide (GSSG) is a disulfide derived from two glutathione molecules. [1] In living cells, glutathione disulfide is reduced into two molecules of glutathione with reducing equivalents from the coenzyme NADPH. This reaction is catalyzed by the enzyme glutathione reductase. [2]

Glutathione Disulfide - an overview | ScienceDirect Topics
Glutathione disulfide (GSSG) is the oxidized state of glutathione. The enzyme glutathione reductase brings GSSG back to GSH and is inducible upon OS. The GSSG/GSH-ratio is often used as a measure of cellular toxicity and OS and appears to be increased in NAFLD progression, indicating depletion of GSH [95,101].
Glutathione-Related Enzymes and Proteins: A Review - PMC
Glutathione occurs in two free forms: the reduced (GSH) thiol and the oxidized (GSSG) disulfide forms (Figure 1). In addition, it can be bound to proteins and other thiols, affecting their activity. In its reduced and oxidized forms (GSH, GSSG), glutathione is ubiquitous in mammalian cells ranging in 1–10 mM concentrations [8].

2023年7月28日 · GSH and its oxidized form glutathione disulfide (GSSG) make up the most important thiol redox buffer in the body, and its homeostasis is critical to many important cellular functions.
Glutathione Disulfide - an overview | ScienceDirect Topics
Glutathione disulfide (GSSG) is formed during the quenching of ROS, and in the presence of enzyme glutathione reductase, GSSG can be reduced back to GSH. The possibility of reusing GSH after preventing oxidative stress makes it a particularly attractive candidate for polymeric antioxidant therapy.

2024年11月19日 · In its reduced (free thiol) form, glutathione is abbreviated 'GSH'. In its oxidized form, glutathione exists as a dimer of two molecules linked by a disulfide group, and is abbreviated 'GSSG'. A new disulfide in a protein forms via a 'disulfide exchange' reaction with GSSG, a process that can be described as a combination of two S N 2-like ...
