超氧化物歧化酶(SOD)广泛存在生物体的各种组织中,它能催化自由基O_2~-生成H_2O_2和O_2;而H_2O_2极易被体内过氧化氢酶分解掉。自由基是体内氧化尚未彻底完成的中间产物,也可由受射线照射或服用各种药物而产生。自由基可破坏机体细胞,活化致癌物而导致肿瘤发生,引起炎症和自身免疫性疾病,并可促使机体衰老。 Bhuyan报导兔眼组织中SOD存在于角
Superoxide dismutase (SOD) widely exists in various tissues of the organism, it can catalyze the free radical O 2 - to generate H 2 O 2 and O 2; and H 2 O 2 is easily decomposed by catalase in the body. Free radicals in the body is not yet completely oxidized intermediates, but also by radiation exposure or taking a variety of drugs generated. Free radicals can damage the body’s cells, activate carcinogens and cause tumors, causing inflammation and autoimmune diseases, and can promote the body’s aging.
