A peptide bond is a type of amide linkage that forms between amino acids. Specifically, it is a chemical covalent bond that joins amino acids together, initiating the formation of polypeptides and ultimately, proteins. The formation of this bond involves the reaction between the carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of another. This reaction, often occurring under physiological conditions with the assistance of enzymes, results in the release of a water molecule – a process known as dehydration synthesis.
