迄今为止,对硒在有机体内的生理生化作用的认识,主要来自于动物研究领域,普遍认为,其主要作用是作为谷胱甘肽过氧化物酶(GSH-Px)和磷脂氢谷胱甘肽过氧化物酶(PHGSH-Px)等含硒酶活性中心的必要组成这一生物活性形式发挥抗氧化作用。薛泰麟等〔1,2〕曾在大豆、油菜、小麦和?.. Until now, the understanding of the physiological and biochemical effects of selenium in the organism has come mainly from the field of animal studies. It is generally believed that its main function is to act as a marker of glutathione peroxidase (GSH-Px) and phospholipid-hydro glutathione Peroxidase (PHGSH-Px) and other selenium-containing enzyme activity of the necessary components of this bioactive form of anti-oxidation.
