锌作为一种微量元素,在体内的作用已受到研究者的重视。早先曾认为锌的基本功能是构成某些含锌金属酶类而发挥作用,但这种假说的基础是不充分的。在严重缺锌的动物,大多数含锌的金属酶类只有少数的活性降低,但却发生明显的病理生理改变。这说明锌所表现的主要生理功能与金属酶活 The role of zinc as a trace element in the body has been the attention of researchers. It was previously thought that the basic function of zinc was to constitute certain zinc-containing metalloenzymes, but the basis of this hypothesis was insufficient. In animals with severe zinc deficiency, only a few of the zinc-containing metalloenzymes have reduced activity, but significant pathophysiological changes have occurred. This shows that the main physiological functions and metalloenzyme activity of zinc
