Protein Stability
Since ΔG° = -RTlnK

a 10-fold decrease in K increases ΔG° by about 10-fold
a 10-fold increase in K decreases ΔG° by about 10-fold
a 10-fold decrease in K decreases ΔG° by about 2.3*RT
a 10-fold increase in K decreases ΔG° by about 2.3*RT

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

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