l histidine

L-Histidine (L-(-)-Histidine) is a semi-essential amino acid (children should obtain it from food) needed in humans for growth and tissue repair, L-Histidine is important for maintenance of myelin sheaths that protect nerve cells and is metabolized to the neurotransmitter histamine. Histamines play many roles in immunity, gastric secretion, and sexual functions. L-Histidine is also required for blood cell manufacture and protects tissues against damage caused by radiation and heavy metals.

Histidine (abbreviated as His or H) is an alpha-amino acid. The L-isomer is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. It is classified as a charged, polar because of the hydrophilic nature of the imidazole side chain.

N-Stearoylhistidine is a bioactive chemical.

N-Acetyl-L-histidine monohydrate (NAH) is a histidine derivative and a prominent biomolecule found in the brain, retina, and lens of poikilothermic (cold-blooded) vertebrates. It functions as an essential animal metabolite and serves as a major osmolyte in the brain and ocular tissues of teleost fish, amphibians, and reptiles. Unlike poikilotherms, homeothermic (endothermic) vertebrates exhibit significantly lower levels of NAH in the brain and other tissues, highlighting its unique phylogenetic distribution and specialized physiological role in evolutionary biology and vertebrate homeostasis.
