Endogenous antioxidants that play an important role in the reduction of reactive oxygen species formed during cell metabolism and sudden breathing. Glutathione-S-transferase catalyzes the formation of glutathione sulfide and xenobiotics, white three Chemicalbook ene and other molecules with electrophilic centers. Glutathione also forms disulfide bonds with cysteine residues in proteins. Through these mechanisms, it can have a peculiar effect of reducing the effectiveness of anticancer agents.
