Notes:
The electrostatic interactions between α-helix dipoles in the crystals of an uncharged helical undecapeptide have been studied in detail. The electrostatic interaction energy between one helix dipole and its 26 nearest neighbors is approximately -23 kcal mol-1. A very similar result is obtained when calculating the interactions between one helix dipole and all 988 helix dipoles occurring within a distance of 75 Å. It therefore appears that in these crystals of completely uncharged molecules large, favorable electrostatic interactions occur.
