Protein Folding Problem And Its Solutions, TheThis book presents a new approach to the Protein Folding Problem. It starts with a clear description of what the protein folding problem involves. Then, it suggests non conventional answers to some of the questions posed. In particular, it emphasizes the importance of hydrophilic interactions and hydrophilic forces, rather than the hydrophobic effects, for the stability of the native structure of proteins, as well for the speed of the folding process.
