Glutathione: Biosynthesis, Functions and Biological Implications

Glutathione (GSH) is a ubiquitous tripeptide (γ-L-glutamyl-L-cysteinyl-glycin) playing an important role in cellular redox homeostasis, defense against electrophilic reactive species, and control of several cellular events, among others. Most of these cellular functions are related to its thiol (SH) function of the cysteine moiety. With increasing knowledge on the molecular basis of its cellular f...
