What is Glutathione??

L-Glutathione Reduced (GSH, γ-L-Glutamyl-L-cysteinylglycine, CAS 70-18-8) is the most abundant intracellular antioxidant tripeptide. Molecular formula C₁₀H₁₇N₃O₆S, MW 307.32 g/mol. GSH is a critical substrate for glutathione peroxidase (GPx), glutathione S-transferase (GST), and glutaredoxin — neutralising reactive oxygen species, detoxifying xenobiotics, and maintaining thiol-redox homeostasis. In research settings, GSH is used to study oxidative stress, immune function, liver detoxification, and the γ-glutamyl cycle (GGT/GSS/GSR pathways).
