On analysis of a protein chain , it was found that it is made up of just a peptide bond. The possible structure of the protein is its

Protein are nitrogeneous organic compound having very high molecular mass. They are polyamide formed from alpha -amino acid. The bond formed between two amino acid is called peptide bond (-underset(O)underset(||)C-NH-) . The product obtained by this peptide bond formation are called peptide and they may be divided as di, tri, tetra, penta peptide. The given structure of amino acid will exist at which pH?
