Solution

Polypeptide chains are long strings of amino acids held together by peptide bonds.
Amino Acids are linked by Peptide Bonds to form Polypeptide chains. Proteins are linear polymers formed by linking the a-carboxyl group of one amino acid to the $\alpha$-amino group of another amino acid with a peptide bond (also called an amide bond). undefined
