Expert Solution
Step 1

Proteins are the polymers of amino acids. The individual amino acids in a polypeptide are joined by the peptide linkages.

The proteins are composed of two or more polypeptide chains. They may be identical or unidentical.

These proteins are called oligomers.

The protein with a single polypeptide is called a monomer.

A protein with two polypeptides is called a dimer. Similarly, the protein with four polypeptides is called a tetramer.
