The guanidino group in arginine’s side chain is the most basic of all R groups (a fact reflected in its pKa value of 12.5). As mentioned above for aspartate and glutamate, the side chains of arginine and lysine also form ionic bonds.

WebThe structure of an amino acid in aqueous solution depends on the environment pH. The major form in neutral solution is the zwitterion. In strong acid (pH < 1), the predominant form is the cationic ammonium carboxylic acid. In strongly basic solutions (pH > 13), the predominant form is the deprotonated 2-aminocarboxylate ion.
