MSH: An essential amino acid that is required for the production of HISTAMINE.,CSP: essential amino acid that contains the imidazole ring system.,NCI: Amino acid with side chain -CH2-C3H3N2.,CHV: An essential amino acid that is required for the production of HISTAMINE,CHV: An essential amino acid that is required for the production of HISTAMINE,CHV: An essential amino acid that is required for the production of HISTAMINE,NCI: 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.
