Abstract:
Hydrogen bonds are essential elements in protein structure and dynamics. We show that such bonds are strongly dominated by entropic contributions of the environment that can be at least as important as energetic considerations. These contributions are global in that they are not due to the internal degrees of freedom. The mol. dynamics (MD) is carried out as a computer expt. and agrees very well with the known energies of hydrogen bonds, both in water and in the isolated mol. The entropy in wate...     »
