Descriptions:
pubchem: Arginine is an alpha-amino acid that is glycine in which the alpha-is substituted by a 3-guanidinopropyl group. It has a role as a fundamental metabolite. It is a member of guanidines, a polar amino acid and an alpha-amino acid. It contains a 3-carbamimidamidopropyl group. It is a conjugate base of an argininium(1+). It is a conjugate acid of an argininate.
chebi: An α-amino acid that is glycine in which the α-is substituted by a 3-guanidinopropyl group.
wikipedia: Arginine is the amino acid with the formula (H2N)(HN)CN(H)(CH2)3CH(NH2)CO2H.  The molecule features a guanidino group appended to a standard amino acid framework. At physiological pH, the carboxylic acid is deprotonated (−CO2−) and both the amino and guanidino groups are protonated, resulting in a cation. Only the L-arginine (symbol Arg or R) enantiomer is found naturally. Arg residues are common components of proteins. It is encoded by the codons CGU, CGC, CGA, CGG, AGA, and AGG. The guanidine group in arginine is the precursor for the biosynthesis of nitric oxide. Like all amino acids, it is a white, water-soluble solid.
The one-letter symbol R was assigned to arginine for its phonetic similarity in English.
