随着放射性同位素和超微量检测技术的应用,对微量元素锌的代谢,已有较多了解。现已发现一些疾病伴有低锌血症(hypozincemia)。实验证明锌对心脏和金属中毒有较好的保护作用。因此,低锌血症已成为临床和实验室研究的新课题。锌代谢的生理锌为人体必需的微量元素,其含量占人体的0.004％左右,仅次于铁。它是去氧核糖核酸(DNA)和核糖核酸(RNA)聚合酶、胸腺嘧啶核苷激酶、碳酸酐酶、碱性磷酸酶和醇脱氢酶等的主要成分,并与肌肽酶、氨肽酶、卵磷脂酶等80种酶的活性有关。在组织呼吸和体内生化过程中占有重要地位。
With the application of radioactive isotopes and ultra-trace detection technology, the metabolism of trace elements zinc has been more understood. It has been found that some diseases have hypozincemia. Experiments show that zinc has a good protective effect on heart and metal poisoning. Therefore, hypoxemia has become a new topic in clinical and laboratory research. Zinc metabolism of physiological zinc for the human body essential trace elements, its content accounts for about 0.004% of the human body, second only to iron. It is the main component of DNA and RNA polymerase, thymidine kinase, carbonic anhydrase, alkaline phosphatase and alcohol dehydrogenase, and with creatine peptidase, aminopeptidase , Lecithin and other 80 enzymes activity. In tissue respiration and biochemical processes occupy an important position.
