Access from EThOS:
Despite considerable effort in understanding electrostatic interactions in proteins, namely a-helices, the literature contains many conflicting descriptions. The loss of conformational entropy associated with helix ~ coil equilibrium is balanced, in part, by electrostatic contributions to enthalpy such as backbone a-helical H-bonds; i->i+3 and i->i+4 side chain H-bonds and salt bridges; side chain-main chain H-bonds and salt bridges, and through-space electrostatic interactions of side chains with the helix-macrodipole. Peptide bonds are 'micro' dipoles which are aligned (97%) with the helix axis resulting in the so-called helix-macrodipole and local dipole effects result at the termini due to dissatisfied H-bond donor and acceptors there.
