Peptide Bonds The sequence and the number of amino acids ultimately determine the proteins shape, size, and function. Once in duodenum, enteropeptidase activates trypsinogen by removing 7-10 amino acid from N-terminal region known as trypsinogen activation peptide (TAP). [3] This restriction is due to the rigid nature of the amide (peptide) bond. When one amino acid combines the carboxyl group of another amino acid, a peptide bond is formed. It need not be the same in all amino acids, and it can be different too. Peptide bonds (also known as amide bonds) are the bonds that are found between two monomer units of amino acids in a polypeptide chain. The chemical/physical changes in disulfide bonds make permanent waving, curl re-forming, and chemical hair relaxing possible. Covalent bonds between amino acids are known as peptide bonds. The resulting CO-NH bond is called a peptide bond, and the resulting molecule is an amide.
