硒的需要硒是谷胱甘肽过氧化酶的基本组成部分,此酶可控制在脂肪代谢过程中产生的对机体有害的脂肪酸过氧化物。当机体有足够的过氧化酶时,就能把脂肪酸过氧化物转变成无害的形式。在硒及该酶缺乏的情况下,脂肪酸过氧化物的量就相应地增加。经证明,这些物质增加的量,可引起血管损伤及血液凝块的发展(血栓形成)。现已证明,脂肪 Selenium needs Selenium is an essential part of glutathione peroxidase, which controls fatty acids peroxides that are harmful to the body during fat metabolism. When the body has enough peroxidase, it can convert fatty acid peroxides into harmless forms. In the absence of selenium and the enzyme, the amount of fatty acid peroxide is correspondingly increased. The increased amount of these agents has been shown to cause vascular damage and the development of blood clots (thrombosis). It has been proved that fat
