硒是一种重要的微量元素.虽然,人体需要硒的量不多,为50微克～200微克/日,最少为20微克～30微克/日.但是,如果人体缺少硒,也会引起一系列的疾病.硒的缺乏,是造成缺硒心肌病、心律失常和纤维性颤动病的原因;硒代谢不平衡,与肿瘤、动脉硬化、某些辐射性疾病、维生素缺乏症、肝中毒、过敏症等病有关.由于硒化合物是一种强抗氧化剂,对某些酶有一定的影响.因此,它能防止氧化酯类自由基链的细胞生物膜的增厚,对防止人体器官的老化具有重要的作用.
Selenium is an important trace element. Although the body needs a small amount of selenium, it is 50 micrograms to 200 micrograms/day, and the minimum is 20 micrograms to 30 micrograms/day. However, if the human body lacks selenium, it can also cause a series of Diseases. The lack of selenium is the cause of selenium-induced cardiomyopathy, arrhythmia and fibrillation; selenium metabolism is imbalanced with tumors, arteriosclerosis, certain radiation diseases, vitamin deficiencies, liver toxicity, allergies. It is related to diseases. Since selenium compounds are a kind of strong antioxidant, they have a certain influence on certain enzymes. Therefore, it can prevent the thickening of cell biofilms of oxidized ester free radical chains and is important for preventing the aging of human organs. The effect of.
