'''Glutathione peroxidase''' (GPX) reduces lipid hydroperoxides to alcohols and free hydrogen peroxide to water. Thus, GPX protects the organism from oxidative damage<ref>PMID:11215509</ref>. There are several isozymes of GPX. Eight isozymes have been found in human.<br />

Low levels of GPX are found in patients of vitiligo, type 2 diabetes and relapsing multiple sclerosis. There is age-related decrease of GPX activity and hence in antioxidant activity. GPX3 is a candidate of inducing anticancer drug resistance in ovarian clear cell adenocarcinoma<ref>PMID:19020706</ref>. GPX4 protects cortical neurons from oxidative injury<ref>PMID:16673405</ref>GPX7 has potential tumor suppressor function<ref>PMID:23580780</ref>.
