... All of the 20 amino acids found in proteins have a carboxyl group and an amino group bonded to the same carbon atom (the a carbon) (Fig. 5-2). They differ from each other in their side chains, or R groups, which vary in structure, size, and electric charge, and influence the solubility of amino acid ...
