微量元素包括锌、铜、锰、铬、硒、钴、钼、氟、铁、碘、镍、锡、硅、钒等,共约14种,在体内含量极少,但在生命和代谢过程中却很重要。过去由于测定困难,了解不多,重视不够。近年来在研究方面已有较大进展,现根据部分文献,作一简述。锌锌在身体组织内,特别在细胞内是金属酶结构的重要成份之一。这些酶包括碳酸酐酶、碱性磷酸酶、胰腺羧肽酶、脱氢酶、醛缩酶、肽酶、转磷酸基酶、天门冬氨酸转氨基甲酰基酶、异构酶、DNA聚合酶等大约70种之多,
Trace elements including zinc, copper, manganese, chromium, selenium, cobalt, molybdenum, fluorine, iron, iodine, nickel, tin, silicon, vanadium, a total of about 14 species in the body content is minimal, but in life and metabolism It is very important. In the past due to the determination of difficulties, little understanding, not enough attention. In recent years, great progress has been made in the research. Based on some documents, a brief review is given. Zinc and zinc in the body tissues, especially in the cell is one of the important components of the structure of metal enzymes. These enzymes include carbonic anhydrase, alkaline phosphatase, pancreatic carboxypeptidase, dehydrogenase, aldolase, peptidase, transphosphatase, aspartate transcarbamylase, isomerase, DNA polymerase About 70 kinds of as much,
