This process involves:<\/p>\n<ol>\n<li>A condensation reaction between the carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of another<\/li>\n<li>Release of a water molecule (H<sub>2<\/sub>O) as a byproduct<\/li>\n<li>Creation of a planar, rigid covalent bond with partial double bond character due to resonance<\/li>\n<\/ol>\n<p>The rigidity of <strong>peptide bond basics<\/strong> restricts rotation around the bond, stabilizing protein structures. This planar nature also enables hydrogen bonding and van der Waals interactions along the peptide chain, shaping proteins\u2019 characteristic 3D conformations.
