The specific heat, Cv, of the Gō model vs. temperature for various pressures, and for the potential-energy function without a desolvation barrier (Upper) is contrasted with the folding denaturation curves (Lower). The specific heat for the model with no desolvation barrier is labeled NB, with Rc = 1.8 and Rc = 1.167, where Rc is the width of the attractive square-well potential.
