1) Hydrophobic means not liking water. Thus most stable folds in many cases
would be those with hydrophobic (also called non-polar) residues not coming
in contact with the water (polar solvent). 2) Hydrophobic residues are known
to protect hydrogen bonds by expelling water molecules that otherwise can
easily brake the forming bonds.
