Summary

Glutathione disulfide (GSSG) is the oxidized dimeric form of the endogenous tripeptide glutathione, linked by a disulfide bond between two cysteine residues.

Mechanism of Action

acts as cellular redox buffer; oxidized form can be reduced back to glutathione, participates in antioxidant defenses
