At its core, peptide bond formation involves the joining of two amino acids. This is achieved through a dehydration synthesis or condensation reaction at a molecular level.Mechanism of peptide bond synthesis on the ribosome In this process, the carboxyl group (-COOH) of one amino acid reacts with the amine group (-NH2) of another. Specifically, the hydroxyl (-OH) group from the carboxyl group and a hydrogen atom (-H) from the amine group are removed, forming a molecule of water (H2O). The remaining carbon atom of the carboxyl group then forms a covalent bond with the nitrogen atom of the amine group, creating the characteristic peptide bond (-CO-NH-)2020年5月30日—Peptide synthesis requires selective acylation of a free amine.
