Über dieses Buch

Diese Monografie stellt die Molekulartheorie und notwendige Werkzeuge für die Untersuchung lösungsmittelinduzierter Wechselwirkungen und Kräfte vor. Nach einer Einführung in die grundlegenden Definitionen lösungsmittelinduzierter Wechselwirkungen liefert der Autor eine kurze Analyse der statistischen Thermodynamik. Das Buch gibt einen gründlichen Überblick über den Zusammenhang dieser Wechselwirkungen mit der Thermodynamik und konzentriert sich daher auf die spezifische Diskussion der hydrophoben-hydrophilen Wechselwirkungen und Kräfte. Die Bedeutung der Implementierung hydrophiler Wechselwirkungen und Kräfte in verschiedenen biochemischen Prozessen wird eingehend analysiert, während Belege auf Grundlage von Theorie, Experimenten und simulierten Berechnungen detailliert beschrieben werden, die belegen, dass hydrophile Wechselwirkungen und Kräfte viel wichtiger sind als die entsprechenden hydrophoben Effekte in vielen biochemischen Prozessen wie Proteinfaltung, Selbstzusammensetzung von Proteinen, molekulare Erkennung. Dieser Titel ist für Studenten und Forscher aus den Bereichen Chemie, Physik, Biochemie und Molekularbiologie von großem Interesse.

Chapter 1. Introduction, Definitions and Motivations for Studying Solvent-Induced Interactions
Abstract
In the first part of this chapter we start by defining the interaction energy between two or more particles in different media and express these interactions in terms of thermodynamic quantities. In the second part, we discuss the motivation for studying these interactions in the context of the so-called protein folding problem (PFP). We shall survey the main historical landmarks in the history of studying solvent-induced interactions (SII) in connection with the PFP.

Chapter 2. A Brief Introduction to Statistical Thermodynamics
Abstract
In this chapter, we present a very brief introduction to some of the fundamental concepts of statistical thermodynamics (ST) that we shall need in this book. We shall not derive any relationship, nor prove any statement.

Chapter 3. Solvent-Induced Interactions and Forces, Definitions and Connections with Thermodynamics
Abstract
In this chapter, we introduce the two main concepts of this book; the solvent-induced interactions (SII) and the solvent-induced forces (SIF). The former is defined as part of the potential of mean force (PMF), and the second is defined as the derivative of the PMF. Following these definitions, we demonstrate the connection between the PMF and thermodynamic functions (either the Helmholtz energy or the Gibbs energy depending on whether we work is done in either T, V, N, or the T, P, N ensemble, respectively). Finally, we show how many confuse the two concepts of SII and SIF.

Chapter 4. Hydrophobic Interactions and Forces
Abstract
As I explained in both the preface and in Chap. 1 of this book, the whole study of the solvent-induced interactions in aqueous solutions was motivated by the protein folding problem and other related processes occurring in aqueous solutions.

Chapter 5. Hydrophilic Interactions and Forces
Abstract
The term “hydrophilic” \(\left( {H\phi I} \right)\) was used long before the term “hydrophobic” was introduced in connection with the problem of protein folding. It should be noted that “water fearing” is not exactly the opposite of “water-loving.”

Chapter 6. Implementation of the Interactions and Forces in Some Biochemical Processes
Abstract
In this Chapter we shall show how the various \(H\phi I\) effects (both interactions and forces) can explain most of the mysteries in protein chemistry. We start with the problem of stability of the 3D structures of proteins, then we discuss the “speed” of the folding process. Next, we discuss the general process of self-assembly of proteins, including the case of in molecular recognition, Finally, we discuss the the solubility of globular proteins, and the phenomenon of cold denaturation of proteins.
