Expert Solution

Step 1

Polypeptides and proteins are organic molecules that occur naturally and are required by cells. They are both made up of amino acids. Amino acids are naturally occurring compounds that produce proteins ,polypeptides, peptides.Each amino acid has one hydroxyl (-COOH) group and amine (-NH2) , as well as a distinct side chain (R group). The R group differs in its charge, shape, size, and reactivity, making each amino acid unique. There are 20 distinct forms of monomeric amino acids that may link together within varying combinations, giving polypeptide chains and proteins a wide range of variation.
