L-Histidine CAS:71-00-1 Histidine 98% With High Quality

L-Hisidine CAS: 71-00-1 is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated –NH3+ form under biological conditions), a carboxylic acid group (which is in the deprotonated –COO− form under biological conditions), and an imidazole side chain (which is partially protonated), classifying it as a positively charged amino acid at physiological pH. Initially thought essential only for infants, it has now been shown in longer-term studies to be essential for adults also. It is encoded by the codons CAU and CAC. L-Hisidine CAS: 71-00-1 was first isolated by German physician Albrecht Kossel and Sven Gustaf Hedin in 1896. It is also a precursor to histamine, a vital inflammatory agent in immune responses. The acyl radical is histidyl. L-Hisidine CAS: 71-00-1 is a semi-essential amino acid (children should obtain it from food) needed in humans for growth and tissue repair. L-Hisidine is important for maintenance of myelin sheaths that protect nerve cells and is metabolized to the neurotransmitter histamine. L-Hisidine play many roles in immunity, gastric secretion, and sexual functions. L-Hisidine is also required for blood cell manufacture and protects tissues against damage caused by radiation and heavy metals. (NCI04) L-histidine CAS: 71-00-1 is the L-enantiomer of the amino acid histidine. It has a role as a nutraceutical, a micronutrient, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a human metabolite, an algal metabolite and a mouse metabolite. It is a proteinogenic amino acid, a histidine and a L-alpha-amino acid. It is a conjugate base of a L-histidinium (1+). It is a conjugate acid of a L-histidinate (1-). It is an enantiomer of a D-histidine. It is a tautomer of a L-histidine zwitterion.
