Protein Stability
The correlation between free energy ΔG transfer between the aqueous/organic phases and the surface area of amino acid residues

reflects the reduction in solvent-accessible area during protein folding
is only meaningful for the polar amino acids
is similar to effects seen with SDS denaturation
ignores the important contribution of the peptide bond
