ECHEMI Editorial Reference

White crystalline or crystalline powder,odorless,slightly bitter taste. Melting and decomposition at about 277~288 ℃. The imidazole and metal ions are easy to form complex salt. Dissolve in water (4.3g/100ml, 25 ℃), very difficult to dissolve in ethanol, insoluble in ether.
It is commonly used for its hydrochloride, because of minimal solubility and other reasons.
Solid|White crystals or crystalline powder; odourless
L-histidine 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.|An essential amino acid that is required for the production of histamine.|Histidine is a semi-essential amino acid (children should obtain it from food) needed in humans for growth and tissue repair, 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. Histidine is also required for blood cell manufacture and protects tissues against damage caused by radiation and heavy metals. (NCI04)|An essential amino acid that is required for the production of HISTAMINE.
