Thermodynamic measurements indicate that native proteins are only marginally stable under physiological conditions. The free energy required to denature them is ∼0.4 kJ ∙ mol−1 per amino acid residue.

Protein stability is the net balance of forces, which determine whether a protein will be in its native folded conformation or a denatured state.

A fully folded 100-residue protein is only about 40 kJ ∙ mol−1 more stable than its unfolded form (for comparison, the energy required to break a typical hydrogen bond is ∼20 kJ ∙ mol−1).

The combined hydrophobic and hydrophilic tendencies of individual amino acid residues in proteins can be expressed as hydropathies. The greater a side chain’s hydropathy, the more likely it is to occupy the interior of a protein.
