Explanation:
Detailed explanation-1: -There are basically four different classes of amino acids determined by different side chains: (1) non-polar and neutral, (2) polar and neutral, (3) acidic and polar, (4) basic and polar.
Detailed explanation-2: -Arginine has guanidine moiety in its side chain hence it is the most basic amino acid.
Detailed explanation-3: -Like other amino acids, glutamine possesses a basic structure consisting of an amino group, a carboxylic acid, and a side chain. In the case of glutamine, a side chain is an amide group, orNH2 N H 2, that is polar in nature. This side-chain possesses a charge of +1.
