explain the structure of protein with the help of diagram!


  • Proteins are polymers of amino acids.

  • Proteins are polypeptides where amino acids are linked by peptide bonds in the form of a linear chain.

  • Proteins are heteropolymers because the polypeptide chain consists of different types of amino acids.

  • Structure of Proteins

  • Proteins are polymers of α-amino acids, joined to each other by peptide linkage or peptide bond.

  • Peptide linkage: Amide formed between −COOH group and −NH2 group of two amino acid molecules.
