This book starts out by presenting the evidence for the importance of hydrophilic interactions in biochemical processes and then goes on to describe the applications of the hydrophilic interactions in these processes, specifically protein folding, protein association, self assembly and molecular recognition.In this volume it is shown that the new paradigm, based on the hydrophilic effect, brings us as close as one can hope to the solutions of the protein folding problem, as well as the problem of self assembly and molecular recognition. In addition, the new paradigm also provides an explanation of the high solubility of globular proteins.The change in the paradigm is shown symbolically in the cover design of this book.
