Product Description

    Histidine is one of the 23 amino acids used to build proteins in humans, known chemically as proteinogenic amino acids. It uses the codons cytosine-adenine-uracil (CAU) and cytosine-adenine-cytosine (CAC). The German physician Albrecht Kossel first isolated histidine in 1896. It was first believed to be an essential amino acid only in infants, although subsequent research has now established histidine as an essential amino acid for all humans.

 Function: 

 Histidine is one of the necessary raw materials for the synthesis of some intermediates, such as ghk-cu. It is now known that major metabolic pathways in organisms include deamination by histidine deaminase, formation of histamine by decarboxylase, and amino transfer reactions. Biosynthesis is from the adenine part of ATP and phosphoribosyl phosphate to form imidazole glycerophosphate for amino conversion reaction.

Application:

1. L-histidine is used in biochemical research, and used in medicine to treat gastric ulcer, anemia, allergies, etc.
2. L-histidine can be used in amino acid drugs. The main component of amino acid infusion and comprehensive amino acid preparation, used to treat gastric ulcer, anemia, angina pectoris, aortitis, cardiac insufficiency and other cardiovascular system diseases.
3. L-histidine is used as a nutritional enhancer and is an important component of amino acid infusion and compound amino acid preparations. Can be used to treat stomach ulcers. Also used in biochemical research.
