Abstract [en]

The structures of the key classes of biological macromolecules: proteins, nucleic acids and polysaccharides can be dissected into very regular motifs, which are alpha-, beta, and double helices and sheets. In this communication we demonstrate that these regular patterns arise as a result of dipole-dipole interactions of the polar groups (peptide, nucleic-acid-base or sugar-ring groups) and the coupling of these interactions with backbone-local interactions, described at the mean-field level; the averaging is carried out by rotating the dipole of a polar unit about its virtual-bond axis.
