Peptide bonds are made between successive amino acids during elongation. This bond is formed between molecules of amino acid. It is formed when the carboxyl group of a molecule reacts with an amino group which releases water. The reaction involved is called dehydration synthesis reaction or condensation reaction. Proteins are commonly the result of this reaction. Proteins consists of amino acids that are bonded by peptide bonds. These bonds are said to be metastable so they would break spontaneously but it is a slow process. These bonds can also be broken by hydrolysis where the bonds are cut by adding water molecules.
