广泛存在于机体中的过氧化氢酶(Cat)对细胞具保护作用,有着重要的生理学功能。需氧脱氢酶作用所产生的与生物氧化过程中所产生的过氧化氢对机体有剧毒。它在超氧离子作用下能产生诱发自由基反应的羟自由基(H_2O_2+O_2~-→OH~-+O_2+HO)。自由基诱导的氧化反应在生物的衰老过程及
Catalase, widely present in the body, protects cells and has important physiological functions. Oxygen dehydrogenase produced by the role of biological oxidation of hydrogen peroxide produced on the body is highly toxic. Under the action of superoxide anion, it can produce hydroxyl radical (H 2 O 2 + - O 2 - → OH ~ - + O 2 + HO) which induces free radical reaction. Free radical induced oxidation reactions in the biological aging process and
