CAS 4998-57-6
:DL-Histidine
Description:
DL-Histidine, with the CAS number 4998-57-6, is a non-essential amino acid that plays a crucial role in various biological processes. It is an imidazole-containing amino acid, which means it has a side chain featuring an imidazole group, contributing to its unique properties. DL-Histidine exists as a zwitterion at physiological pH, possessing both a positively charged amino group and a negatively charged carboxyl group, which enhances its solubility in water. This amino acid is important for the synthesis of proteins and serves as a precursor for histamine, a vital neurotransmitter involved in immune responses and gastric acid secretion. Additionally, histidine is involved in metal ion coordination, making it significant in enzyme catalysis and metalloprotein function. Its buffering capacity is particularly valuable in maintaining pH balance in biological systems. DL-Histidine can be found in various dietary sources, including meat, fish, dairy products, and certain grains, and is often used in nutritional supplements and pharmaceutical formulations.

CAS:<p>DL-Histidine is an enantiopure antibiotic complex that is a proton donor. It is primarily used to treat bacterial infections. DL-Histidine inhibits bacterial growth by acting as a competitive inhibitor of the proton donor in the enzyme histidine decarboxylase and preventing the production of histamine, which is required for bacterial cell division. The molecular modeling study showed that DL-histidine has a linear plot with a high signal detection level, which makes it suitable for sample preparation. The crystalline cellulose molecule was found to form hydrogen bonds with the histidine molecule, which may have an effect on its activity.</p>Formula:C6H9N3O2Purity:Min. 95%Color and Shape:White PowderMolecular weight:155.15 g/molDL-Histidine extrapure, 99%
