Inhibitors and Activators of SOD, GSH‐Px, and CAT

Reactive oxygen species (ROS) is harmful to our health, and SOD, CAT, and GPX are the major antioxidant enzymes that defend us from effects of ROS. In medicine, food, and dairy industries, antioxidant enzymes often surround complex environments. For better utilization of these enzymes, the inhibitors (including competitive inhibitors and noncompetitive inhibitors) and activators of SOD, CAT, and GPX are descripted in detail in this chapter. Also, the structure and catalytic mechanism of these antioxidants are summarized.
