Arginine is the amino acid with the formula (H 2 N)(HN)CN(H)(CH 2) 3 CH(NH 2)CO 2 H. The molecule features a guanidino group appended to a standard amino acid framework. At physiological pH, the carboxylic acid is deprotonated (−CO 2 −) and both the amino and guanidino groups are protonated, resulting in a cation.
The non-essential amino acid arginine, consumed in sufficient amounts, is thought to act as a donor for the synthesis of nitric oxide, a vasodilator. A review confirmed blood pressure lowering. [38] Taurine, a popular dietary supplement ingredient with claims made for sports performance, is technically not an amino acid.
L-Arginine is the substrate of eNOS, and the main precursor of NO in the vascular endothelium. Clinical studies suggest that l-arginine improves endothelial function in the presence of certain atherosclerosis risk factors such as hypercholesterolemia, smoking and possibly hypertension.
