Gastric zinc

Normal adults contain about 2.9g of zinc, which are mainly distributed in the prostate, liver, kidney and muscle. The physiological function of zinc is not only an essential component of a variety of enzymes, such as carbonic anhydrase, alcohol dehydrogenase, carboxypeptidase, aldolase, ribonucleic acid, and DNA polymerase of red blood cells, but also can interact with the thiol group of membrane proteins. , Carboxyl groups, phospholipid phosphates, and sialic acid carboxyl groups in glycoproteins to stabilize membrane structure and prevent membrane lipids from peroxidation, thereby maintaining the normal physiological state of the body. Zinc is absorbed by intestinal mucosal cells and combines with serum proteins to enter the blood, which is mainly excreted by feces.
