The chemical name for Lysine is 2, 6-diaminohexanoic acid. Lysine is a basic essential amino acid. Because lysine content in cereal food is very low, and in the process of processing is easy to destroy and lack, so it is called the first restricted amino acid. Lysine is one of the essential amino acids for humans and mammals, which cannot be synthesized by the body itself and must be supplemented from food. Lysine is found mainly in animal foods and legumes, and is very low in cereals. Lysine has positive nutritional significance in promoting human growth and development, enhancing body immunity, anti-virus, promoting fat oxidation, relieving anxiety and other aspects. At the same time, it can also promote the absorption of some nutrients, and can cooperate with some nutrients to better play the physiological functions of various nutrients.Lysine regulates the body's metabolic balance. Lysine provides the structural components for the synthesis of carnitine, which promotes the synthesis of fatty acids in cells. Adding a small amount of lysine to food can stimulate the secretion of pepsin and gastric acid, improve the secretion of gastric juice, and play a role in increasing appetite and promoting the growth and development of children. Lysine also improves calcium absorption and its accumulation in the body, speeding bone growth. Such as lack of lysine, will cause gastric secretion of insufficient anorexia, nutritional anemia, resulting in central nervous system obstruction, dysplasia. In medicine, lysine can also be used as an auxiliary diuretic drug to treat lead poisoning caused by the reduction of chloride in the blood. It can also be used with acid drugs (such as salicylic acid, etc.) to form salt to reduce adverse reactions. Combined with methionine, it can inhibit severe hypertension.Lysine, as an essential amino acid, is involved in the synthesis of skeletal muscle, enzymes, serum proteins, polypeptide hormones and other proteins in the body. Promotes mineral absorption and bone growth Lysine can chelate with calcium, iron and other mineral elements to form soluble small molecular monomer, and promote the absorption of these mineral elements. Boost immune function Lysine is considered to be a nonspecific bridge molecule, which can bind antigens to T cells and cause T cells to produce specific effects on the antigen. Treat herpes simplex virus infection Studies have also found that lysine supplementation can treat herpes simplex virus infection.
