L-lysine is one of the eight essential amino acids of human body. It is white crystal or crystalline powder, odorless and sweet. Because pure lysine is easy to absorb moisture and agglomerate, it is often made into hydrochloride for convenient separation, purification and application. It is soluble in water, almost insoluble in ethanol and ether, and decomposes when it is co heated with reducing sugar such as glucose to produce an attractive bread flavor. Nutritionists list it as "the first lack of amino acids".
It can promote human development, enhance immune function and improve the function of central nervous system. It is a brain protective agent for the treatment of craniocerebral trauma, chronic cerebral ischemia and hypoxic diseases.
Amino acid drugs can promote children's growth and development, enhance appetite and gastric acid secretion, and are used for children's recovery after illness and pregnancy and lactation. In addition, it also depends on amino acid derivatives and compound preparations, which are amino acid drugs.
