占人体重不到1%的微量元素,在体内起着重要的生理作用:如在酶系统中,微量元素固定在酶的活性部位,作为该部位的几何控制,使得只有具有特定构型的底物才能和它作用;在辅酶中的元素,通过它们的配位作用,能够激活酶和底物。在激素中,微量元素参与激素起调节生理功能的作用。在遗传信息的携带者——核酸中,含有较高浓度的微量元素,体外试验表明:这些元素可能影响着核酸的代谢。
Trace elements, which make up less than 1% of body weight, play an important physiological role in the body: in the enzyme system, trace elements are immobilized on the active site of the enzyme as geometric control of the site so that only the end with a specific configuration The substance can interact with it; the elements in the coenzyme, through their coordination, are able to activate enzymes and substrates. In hormones, trace elements participate in the role of hormones in regulating physiological functions. In the carrier of genetic information - nucleic acid, contains higher concentrations of trace elements, in vitro experiments show that: these elements may affect the nucleic acid metabolism.
