L- histidine is a kind of semi essential amino acids, it is particularly important for infants and animal growth.
Application:
It can be used as a nutrient enhancer, it is an important component of amino acid transfusion and compound amino acid preparation. It can be used for the treatment of gastric ulcer. It can be used to treat heart disease, anemia and rheumatoid arthritis, it can also be used as a biochemical reagent and drug.
Properties: white crystal or crystalline powder. Odorless.It has slightly bitter taste. It will be melted and decomposed in 177-288℃. It is soluble in water, difficultly soluble in ethanol and insoluble in ether. Because the solubility is extreme little, its common form is its hydrochloride.
