Histidine, an alpha-amino acid with the formula C6H9N3O2, was first isolated in 1896 by the German physicist Abbrecht Kossel. In the context of nutrition, histidine is considered an essential amino acid for humans, primarily for children. In adulthood, humans begin to synthesize histidine on their own. When a small amount of histidine is added to the diet of patients with chronic uremia, the rate of amino acid binding into hemoglobin increases, and nephrogenic anemia is reduced, so histidine is also an essential amino acid for patients with uremia. Under the action of histidine decarboxylase, histidine decarboxylase forms histamine. Histamine has a strong vasodilator effect and is associated with a variety of allergic reactions and inflammation. [2] In addition, histamine stimulates pepsin and stomach acid.

Amino acid infusion and comprehensive amino acid preparation is an important component, used in medicine for the treatment of gastric ulcer, anemia, allergy and so on.
On the other hand, imidazolyl gives and receives protons very fast, with a half-life of less than 10-10s, and gives and receives protons almost equally fast. Histidine residues are often active centers in active proteins. Histidine is a semi-essential amino acid, which can be used as a drug or biochemical reagent. For the human body, histidine can be synthesized by ordinary intermediate metabolites, so it has always been considered as a non-essential amino acid. However, with the in-depth research, it has been found that the amount of histidine synthesis in young animals and infants cannot meet the growth needs of the body. Even for adult animals, if they are not supplemented from food, the amount synthesized in the body cannot meet the needs. So they call it a semi-essential amino acid.
Histidine is also one of the essential raw materials for the synthesis of some pharmaceutical intermediates, such as the blue copper peptide ghk-cu.
It has been known that the main metabolic pathways in living organisms are deamination by histidine deaminase, histamine formation by decarboxylase, and amino transfer reaction. Biosynthesis is from the adenine portion of ATP and phosphoribose filament H3PO4 to imidazole glycerol H3PO4, which is converted to amino acid.
L-histidine is a semi-essential amino acid, which is especially important for the development of infants and animals. Can be used as biochemical reagent and pharmaceutical, can also be used to treat heart disease, anemia, rheumatoid arthritis and other drugs. Histidine is found in bananas, grapes, meat, livestock, milk and dairy products. In addition, histidine is also found in green vegetables, but in smaller amounts.
