glutathione metabolic process (GO:0006749)

The chemical reactions and pathways involving glutathione the tripeptide glutamylcysteinylglycine, which acts as a coenzyme for some enzymes and as an antioxidant in the protection of sulfhydryl groups in enzymes and other proteins; it has a specific role in the reduction of hydrogen peroxide (H2O2 and oxidized ascorbate, and it participates in the gamma glutamyl cycle.
