Glutathione peroxidase (GPx) is a vital antioxidant enzyme that protects cells from oxidative damage by catalyzing the reduction of harmful peroxides. The primary reaction it catalyzes involves hydrogen peroxide (H₂O₂) or organic hydroperoxides (ROOH) as substrates and reduced glutathione (GSH) as an electron donor. In this reaction, GPx facilitates the conversion of hydrogen peroxide into water and organic hydroperoxides into their corresponding alcohols, simultaneously oxidizing two molecules of glutathione into glutathione
