Molecular pathways of generation and detoxification of reactive oxygen species and induction of apoptosis in yeasts Arabian Journal of Chemistry TJ. Glutathione peroxidase is an important enzyme in cellular antioxidant defense systems, detoxifying peroxides and hydroperoxides. As a component of the glutathione cycle, it protects the liver from reactive oxygen metabolites.
