Answer» Correct Answer - D The peptide linkage `(-NH-CO-)` is formed by the condensation of amino acid molecules. `HNH-underset(R)underset(|)CH-underset(O)underset(||)C-OH + H . NH-underset(R)underset(|)CH-underset(O)underset(||)C-OH` `overset(-H_(2)O)rarr-HN-underset(R)underset(|)CH-underset(O)underset(||)C-NH- underset(R)underset(|)CH-underset(O)underset(||)C-` Hence, following structure represents the peptide chain `-overset(H)overset(|)N-underset (|)overset(|)C-underset(O)underset(||)C-overset(H)overset(|)N-underset(|)overset(|)C-underset(O)underset(||)C-overset(H)overset(|)N-underset(|)overset(|)C-overset(O)overset(||)C-` |
