Detailed explanation-1: -Each amino acid is identical except for its side chain, or R group. It is the charge, shape, polarity, and size of a side chain that gives each amino acid its unique biochemical properties. Amino acid side chains are typically grouped into non-polar, polar, acidic, and basic categories.
Detailed explanation-2: -The chemistry of amino acid side chains is critical to protein structure because these side chains can bond with one another to hold a length of protein in a certain shape or conformation. Charged amino acid side chains can form ionic bonds, and polar amino acids are capable of forming hydrogen bonds.
Detailed explanation-3: -The amino acids differ from each other in the particular chemical structure of the R group.
