锌是维持机体正常代谢所必需的微量元素。1869年首次证明锌对黑曲霉菌的生长是必需的。1926年确认高级植物的生长需要锌。1954年又证明维持大鼠的健康生长锌是必不可少的。1961年Prasad首先在伊朗乡村发现人类的锌缺乏病。1963年在埃及经过详细的研究证实了这一事实。近年来又发现不少疾病存在低锌血症,并对锌缺乏与某些疾病的关系有了进一步的认识。因此,有关锌在体内的作用已日益受到人们的重视。本文拟就锌的代谢过程和生化、生理作用作一简述。锌的分布、吸收和排泄成人体内含锌总量约为1.4～2.3g,几乎分布在各种组织中。骨骼、皮肤、头发、精子、前列腺、视网膜、胰β细胞等组织中含量较高;肝、肾及骨骼肌含量
Zinc is necessary to maintain the body’s normal metabolism of trace elements. It was first shown in 1869 that zinc was necessary for the growth of Aspergillus niger. 1926 Recognition of the growth of higher plants requires zinc. In 1954, it was proved that maintaining healthy zinc in rats was indispensable. Prasad first discovered human zinc deficiency in Iranian villages in 1961. This fact was confirmed in 1963 by a detailed study in Egypt. In recent years, many diseases also found that there is low zinc deficiency, and the relationship between zinc deficiency and certain diseases have further understanding. Therefore, the role of zinc in the body has been increasingly valued by people. In this paper, the metabolic process of zinc and biochemical, physiological role of a brief review. Zinc distribution, absorption and excretion of zinc in adults total about 1.4 ~ 2.3g, almost distributed in various tissues. Bone, skin, hair, sperm, prostate, retina, pancreatic β-cell and other tissues in high levels; liver, kidney and skeletal muscle content
