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] Antioxidant enzymes, such as glutathione peroxidases and peroxiredoxins, generate glutathione disulfide during the reduction of peroxides such as hydrogen peroxide (H₂O₂) and organic hydroperoxides (ROOH):^[3]

2 GSH + ROOH → GSSG + ROH + H₂O

Other enzymes, such as glutaredoxins, generate glutathione disulfide through thiol-disulfide exchange with protein disulfide bonds or other low molecular mass compounds, such as coenzyme A disulfide or dehydroascorbic acid.^[4]

2 GSH + R-S-S-R → GSSG + 2 RSH

The GSH:GSSG ratio is therefore an important bioindicator of cellular health, with a higher ratio signifying less oxidative stress in the organism. A lower ratio may even be indicative of neurodegenerative diseases, such as Parkinson's disease (PD) and Alzheimer's disease.^[5]

Neuromodulator

GSSG, along with glutathione and S-nitrosoglutathione (GSNO), have been found to bind to the glutamate recognition site of the NMDA and AMPA receptors (via their γ-glutamyl moieties), and may be endogenous neuromodulators.^[6]^[7] At millimolar concentrations, they may also modulate the redox state of the NMDA receptor complex.^[7]

酸化型グルタチオン。
グルタチオン(GSH)の酸化型(GSSG)である。酸化型グルタチオン、あるいはグルタチオンジスルフィドと呼ばれる。眼内に投与されたオキシグルタチオンは組織に取り込まれグルタチオン還元酵素によりグルタチオンとなり、組織のH2O2の除去などをおこなう。眼内灌流液にオキシグルタチオンを添加することで、角膜保護作用、血液房水柵破壊抑制作用、水晶体透明性維持作用、網膜機能維持作用の効果が期待できる。
