Marginal stability protein

WebThe net stability of a protein is quite marginal. All three features, the hydrophobic effect, van der Waals, and H-bonds are required to overcome the very favorable change in conformational entropy when a protein unfolds. This delicate balance is illustrated in the following diagram.
