Origin of Entropy Convergence in Hydrophobic Hydration and Protein Folding

Origin of Entropy Convergence in Hydrophobic Hydration and Protein Folding

An information theory model is used to construct a molecular explanation why hydrophobic solvation entropies measured in calorimetry of protein unfolding converge at a common temperature. The entropy convergence follows from the weak temperature dependence of occupancy fluctuations for molecular-scale volumes in water. The macroscopic expression of the contrasting entropic …
