A protein is a unique three dimensional biological polymer constructed from 20 different monomers called amino acid. Some of amino acids are glycine, alanine, valine, leucine etc. There are three structural levels in the conformation of a protein called primary, secondary, and tertiary structure. Primary structure is the unique genetically coded sequence of amino acids within a protein. Amino acids are bonded by peptide bond which links the amino group of one amino acid with the carboxyl group of another, yielding a polymer of amino acid called polypeptide. …
