A peptide bond is a covalent bond that links amino acids together to create proteins. The chains that are produced are called polypeptide chains. A peptide bond forms by the condensation reactions between the acids. In this image the large red structures represent the R group of the Amino acid. The R group represents and organic variable. This organic molecule is different in each of the 20 amino acids and determines their behavior.

| The primary structure of a protein molecule is the number and sequence of the various amino acids in the polypeptide chain. It is the "recipe" of the protein. Every kind of protein has a different primary structure. ; |  |
