Application:  
It is a very important component of amino acid infusion and comprehensive amino acid preparation. It is used in medicine to treat gastric ulcer, anemia, allergy and so on.

On the other hand, the imidazole Group supplies and receives protons very fast, the half-life is less than 10-10s, and the speeds of supplying and receiving protons are almost the same. Histidine residues are often active centers in active proteins. Histidine is a semi essential amino acid and can be used as a drug or biochemical reagent. For human body, histidine can be synthesized from common intermediate metabolites, so it has always been considered as a non essential amino acid. However, with the deepening of research, it is found that the amount of histidine synthesis in young animals and infants can not meet the growth needs of the body. Even adult animals can not meet the needs if they are not supplemented from food, Therefore, it is also called semi essential amino acid.

Histidine is also one of the necessary raw materials for the synthesis of some pharmaceutical intermediates, such as blue copper peptide GHK Cu

It has been known that the main metabolic pathways in organisms are deamination by histidine deaminase, histamine formation by decarboxylase and amino transfer reaction. Biosynthesis is to form imidazole glycerophosphate from adenine part of ATP and phosphoribosyl filament phosphate for amino conversion reaction.

L-histidine is a semi essential amino acid, which is particularly important for the growth of infants and animals. It can be used as biochemical reagent and medicament. It can also be used to treat heart disease, anemia, rheumatoid arthritis and so on. Histidine is found in bananas, grapes, meat, livestock, milk and dairy products. In addition, histidine also exists in green vegetables, but the content is less.
