Protein are nitrogeneous organic compound having very high molecular mass. They are polyamides formed from `alpha`-amino acid. The bond formed between two amino acid is called peptide bond `-underset(O) underset(||)C-NH-`. The product obtainded by this peptide bond formation are called peptide and they may be divided as di, tri ,tetra, penta peptide.
