What do peptide bonds hold together?

Posted March 21, 2023


Peptide bonds covalently hold 2 amino acids together, forming a dipeptide. A dipeptide is formed by a reaction between alpha carboxyl and alpha amino groups of two amino acids. Another name for this bond is an amide bond. A protein consists of multiple peptide bonds of amino acids linked together to form one or more polypeptide chains. Adding more amino acids can also create oligopeptides.
