硒(Se)是人体必需微量元素,在营养生理学允许量范围内,硒能阻止或延缓病毒、化学致癌物对肿瘤的诱发而产生的致癌作用。谷胱甘肽过氧化物酶(GSH—PX)是硒依赖性的,硒作为谷胱甘肽过氧化物酶的一种重要成分来还原脂质氢过氧化物,使还原型谷胱甘肽(GSH)转变成氧化型谷胱甘肽(GSSG),这样就可破坏脂质氢过氧化物对机体带来的损害,保护细胞膜和组织对抗脂质过氧化反应所引起的破坏作用,维持细胞正常的生物功能。
Selenium (Se) is an essential trace element in the human body. Selenium can prevent or delay the carcinogenic effects caused by viruses and chemical carcinogens to tumors induced by nutrition physiology. Glutathione peroxidase (GSH-PX) is selenium-dependent and selenium acts as an important component of glutathione peroxidase to reduce lipid hydroperoxides so that reduced glutathione (GSH) into oxidized glutathione (GSSG), thus undermining the damage caused by lipid hydroperoxides to the body, protecting cell membranes and tissues against the damaging effects of lipid peroxidation, maintaining the cells Normal biological function.
