Glutathione peroxidase: The Antioxidant Enzyme Family
Glutathione peroxidase (GPx) is a family of enzymes that catalyze the reduction of hydrogen peroxide (H2O2) and organic hydroperoxides to water and alcohols, respectively, using glutathione (GSH) as a cofactor. GPx plays a crucial role in protecting the cells from oxidative damage caused by reactive oxygen species (ROS), which are generated during normal metabolism or…
