Glutathione GSH peroxidases are a family of enzymes whose major function is to protect cells from oxidative damage 2 GSH glutathione H2O2 - GS-SG 2 H2O. myeloperoxidase conves H2O2 to a highly reactive compound hypochlorite Superoxide dismutase conves superoxide into H2O2 ref robbins basic pathology 9th ed page 15
