Nina [5.8K]

Proteins are polymers of amino acids. There are a fixed set of amino acids that are involved in the making of a protein. These amino acids are varied in number and type to give rise to different combinations in a polymer. This creates a diversity of protein molecules.

The amino acids link to other amino acid in the polymer through the formation of a peptide bond between them. It forms when the carboxylic group of one amino acid molecule reacts and binds to the amino group of the other molecule.
