What is Histidine？
Histidine is an alpha-amino acid with the chemical formula C6H9N3O2 and is one of the biological Essential amino acid. It was first isolated in 1896 by a German physicist Albrecht Kossel. Histidine is known nutritionally as a human Essential amino acid, and is particularly important for child growth and development. In adulthood, humans can synthesize histidine on their own.
Histidine is a natural l-type chiral α-amino acid. It is one of the aromatic amino acid, similar to L-Phenylalanine, tyrosine and tryptophan. It has a basic group, the imidazole ring, which determines its aroma and chemical property. Histidine plays an important role in many biochemical reactions in organisms, such as decarboxylation, formation of redox and histamine.

From pig and cow blood. Pig blood powder was prepared by spray drying, about 18kg for every 100kg of pig blood. L-histidine is commonly used as its hydrochloride ([7048-02-4]). The eluent containing l-histidine was concentrated until crystallization appeared, and the pH value was adjusted to 2.5 with hydrochloric acid while hot. Ethanol twice the solution amount was added immediately, and then it was allowed to stand, precipitate and filter to obtain the crude product of l-histidine hydrochloride, which was decolorized, recrystallized and dried. L-histidine can also be extracted from the hydrolyzed products of degreased soybeans.
It is an important component of amino acid infusion and compound amino acid preparation. It can be used to treat gastric ulcer. It's also used in biochemical research
