Definition


A peptide bond guarantees the link between multiple amino acids in order to create what is called a peptide. When there are 21 amino acids in the link, only one type of bond is possible: a peptide bond. This is an amide bond, formed by a dehydration process between two amino acids transported by transfer RNA (ribonucleic acid) molecules. The bond is composed of four atoms: carbon (C), oxygen (O), nitrogen (N), and hydrogen (H). The binding process is reversible, and can even be broken by proteolysis.
