   The antioxidant enzyme defense system is an important barrier by which cells resist reactive oxygen species-induced damage. Superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px/GPx) form a continuous reaction chain that removes superoxide anions, hydrogen peroxide, and ...
