Peptide bond formation is a condensation reaction wherein the carboxyl group of one amino acid links to the amino group of another via dehydration synthesis, resulting in a covalent amide linkage characterized by partial double-bond character due to resonance stabilization. This structural motif serves as the fundamental repeating unit defining polypeptides and proteins within biological chemistry, establishing specific N-terminal and C-terminal polarity that dictates primary sequence notation. The concept fundamentally addresses the mechanism of protein polymerization and its implications for molecular topology in living systems.
