Entropy of Mixing, Hydrophobic Effect and Protein Folding

A new theory of entropy of mixing that entropy of mixing or entropy of assembling increases continuously with the increase in the similarity of the components, has been developed based on the abandoning of the conventional statistical mechanics theory of mixing process [1-3]. This theory has given a perfect explanation of the process spontaneity of the hydrophobic effect and the protein folding phenomena. It also provided foundation for quantitative calculation of changes of thermodynamic parameters, particularly entropy and free energy.
