Peptide bonds are central to protein structure, linking amino acids to form polypeptides. These covalent bonds, characterized by partial double bond nature due to resonance, confer rigidity and planarity, essential for the protein's functional three-dimensional shape. Understanding peptide bond formation and hydrolysis is crucial for insights into protein synthesis and degradation, impacting biological activity and cellular regulation.
