WebThe covalent bond between amino acids is called a peptide bond. Therefore, proteins are sometimes called polypeptides. The 20 amino acids have the same basic format, differing only in what is known as the R group. H-bonds and covalent bonds between S atoms of the R groups give proteins their shapes and functional properties. WebIn order to maintain the structural integrity and stability of biomolecules like proteins and nucleic acids, hydrogen bonds and van der Waals interactions are essential for cells.
