Subject: WSN: free energies calculstions

	Hi Netter's,
	I would like some references which calculate or measure the free 
energy change (DG) in transfering an alanine or glycine from water to a 
nonpolar solvent and the free energy change for the transfer of a valine 
from the same nonpolar solvent to water, all this to have an idea (quite 
approximated) about the ratio between the DG of a hydrogen bond and the 
DG of a hidrophobic interaction.
	I know that the data I'm asking for is not enough to adress my 
problem but it may be seen as a first aproximation.
	Sincerly yours,
				Rafael.
