锌是植物、动物和人必需的微量营养元素之一。随着人们对锌的重要性的认识及有关科学实验研究,锌在临床上的意义已日益引起人们的注意。一、锌的生理功能锌有多方面的功能。它是人体正常生长发育过程所必需的微量元素,是很多种金属酶的组成成分或酶的激活剂,现在已知与锌有关的酶不下20种,例如碳酸酐酶、碱性磷酸酶、醇脱氢酶、乳酸脱氢酶、谷氨酸脱氢酶、胸腺嘧啶核苷激酶及羧肽酶等。锌是胰岛素的成分,每一个胰岛素中有两个锌原子,可能与胰岛素的活性有关。锌能协助葡萄糖在细胞膜上运转,在对糖类的消化和磷的代谢上都起着极重要的作用。锌与核酸蛋白质的合成,与维生
Zinc is one of the micronutrients essential for plants, animals and people. With the people’s understanding of the importance of zinc and related scientific experiments, the clinical significance of zinc has drawn increasing attention. First, the physiological function of zinc Zinc has many functions. It is a trace element essential for the normal growth and development of the human body and is a component of many kinds of metalloenzyme or an activator of enzymes. No less than 20 kinds of enzymes related to zinc are now known, for example, carbonic anhydrase, alkaline phosphatase, alcohol Dehydrogenase, lactate dehydrogenase, glutamate dehydrogenase, thymidine kinase and carboxypeptidase. Zinc is a component of insulin. There are two zinc atoms in each insulin, which may be related to the activity of insulin. Zinc can help glucose in the cell membrane in the digestion of carbohydrates and phosphorus metabolism plays a vital role. Zinc and nucleic acid protein synthesis, and maintenance
