Peptide Bond: Definition, Structure, Mechanism, and Examples

WebIt occurs when the carboxylic group of one molecule reacts with the amino group of the other molecule, linking the two molecules and releasing a water molecule. Long chain polypeptides can be formed by linking many amino acids to each other via peptide bonds. Dipeptides are produced by coupling amino acids. The amino group on one amino acid is rendered non-nucleophilic (P in eq) and the carboxylic acid group in the second amino acid is deactivated as its methyl ester. The two modified amino acids are then combined in the presence of a coupling agent, which facilitates formation of the amide bond: RCH(NHP)CO2H + R'CH(NH2)CO2CH3 → RCH(NHP)C(O)NH(CHR')CO2CH3 + H2O WebNow imagine doing the same thing with a simple dipeptide made of any two amino acids.
