Define the following as related to proteins : primary structure

Explanation

Primary structure : The primary structure of protein is defined as the linear sequence of amino acid residues making up its polypeptide chain. Proteins may be formed of one or more polypeptide chains. The amino acid residues are linked by peptide bonds . The peptide bond is formed between carboxyl group of one amino acid and amino group of adjacent amino acid. Eg: Fibroin of silk.
