Book Description
This book deals with energetics of transport processes, largely expressed in terms of the thermodynamics of irreversible pro cesses. Since at the present time too little is known about the molecular mechanism of transport, the present treatment is based largely on hypothetical models. Care has been taken, however, to define the crucial features of these models as generally as pos sible, so that the equations do not depend too much on hypotheti cal details. Accordingly, most equations, though developed on the basis of a mobile carrier (ferryboat) model, should apply equally to a conformational model, with an appropriate reinterpretation of the symbols. To better elucidate the essentials, the models are greatly simplified by special assumptions. Maximally, only two flows are assumed to be present in each model at one time: e. g. , two solute flows, the flow of solvent and of one solute, the flow of solvent and of heat. The simplifying assumptions may often be unreal. Hence the equations should not be applied un critically to actual mechanisms. They may at best serve as a ba sis on which the more appropriate equations may be developed. The book is not designed to give a complete kinetic analysis of the transport processes described. The kinetic equations are kept to the minimum required to describe the model concerned and to relate it to the corresponding thermodynamic equations. The in tention is to stress the close relationship between bioosmotic (transport) and biochemical processes in metabolism.

Book Description
An overview of recent experimental and theoretical developments in the field of the physics of membranes, including new insights from the past decade. The author uses classical thermal physics and physical chemistry to explain our current understanding of the membrane. He looks at domain and 'raft' formation, and discusses it in the context of thermal fluctuations that express themselves in heat capacity and elastic constants. Further topics are lipid-protein interactions, protein binding, and the effect of sterols and anesthetics. Many seemingly unrelated properties of membranes are shown to be intimately intertwined, leading for instance to a coupling between membrane state, domain formation and vesicular shape. This also applies to non-equilibrium phenomena like the propagation of density pulses during nerve activity. Also included is a discussion of the application of computer simulations on membranes. For both students and researchers of biophysics, biochemistry, physical chemistry, and soft matter physics.

Book Description
Thermodynamics of Membrane Receptors and Channels synthesizes a wealth of new information regarding the biophysics of membrane proteins. New insights provided by molecular genetics, single channel recording, and high resolution structural techniques are discussed from a conceptual perspective. Basic theoretical topics are introduced, developed, and then extensively illustrated with recent results from the literature or data from the authors' own laboratories. Theoretical and experimental information is incorporated into in-depth discussions of ion permeation mechanisms, ion channel and receptor conformational changes, aggregate activity of complexes of lipids and proteins, and how coupling is achieved between different energy modes in the many transduction systems residing in biomembranes. Thermodynamics of Membrane Receptors and Channels will be valuable both as a learning aid and a reference for biophysicists, neuroscientists, cell biologists, physiologists, and other researchers investigating any aspects of biomembranes.

Book Description
Ls book is an account of what physical chemistry h . . to say about the structural, electrical and transport properties of biological membranes and their simplest model-the lipid bilayer. The accent throughout is on basic ideas. In contrast to the essentially descriptive ap proach characteristic of texts on membrane biochemistry, our underlying themes are the role of force and entropy in maintaining membrane organization, in determining the electric fields and ionic environment of membranes, and in regulating the passage of molecules and ions across membranes. Although experimental findings will always be the touch stone against which theory will be tried, no attempt is made to present an exhaustive survey of experimental data. On the other hand, there is discussion of the nature and limitations of the results obtainable by the major laboratory techniques. The treatment is at the level of an advanced undergraduate course or an introductory survey suitable for post graduate students carrying out research in biochemistry, biophysics, or physiology. The mathematical demands on the reader are trivial. The few forbidding equations appearing in Chapter 7 are soon whittled away to simple practical expressions. Although the current-voltage characteristics of nerves are traditionally the province of biophysics rather than physical chemistry, certain aspects relevant to the electrical activity of nerves are nevertheless included in this text, namely, mem brane and diffusion potentials and conductivity fluctuations. Where rival theories exist, conflicting convictions have been presented, but not necessarily accorded equal approbation. The author has a viewpoint.

Book Description
This book mainly focuses on key aspects of biomembranes that have emerged over the past 15 years. It covers static and dynamic descriptions, as well as modeling for membrane organization and shape at the local and global (at the cell level) scale. It also discusses several new developments in non-equilibrium aspects that have not yet been covered elsewhere. Biological membranes are the seat of interactions between cells and the rest of the world, and internally, they are at the core of complex dynamic reorganizations and chemical reactions. Despite the long tradition of membrane research in biophysics, the physics of cell membranes as well as of biomimetic or synthetic membranes is a rapidly developing field. Though successful books have already been published on this topic over the past decades, none include the most recent advances. Additionally, in this domain, the traditional distinction between biological and physical approaches tends to blur. This book gathers the most recent advances in this area, and will benefit biologists and physicists alike.

Book Description
This book describes how biologically available free energy sources (ATP, chemical potential, and membrane potentials, among others) can be used to drive synthetic reactions, signaling in cells, and various types of motion such as membrane traffic, active transport, and cell locomotion. As such, it approaches the concept of the energy cycle of life on Earth from a physical point of view, covering topics ranging from an introduction to chemical evolution, to an examination of the catalytic activity of enzymes associated with the genome in Darwinian evolution. The author introduces the relationship between functions and physical properties in biomembranes, explaining the methods and equipment used in biophysics research to help researchers unravel the still-unsolved mysteries of life. The physical principles needed to understand the cellular functions are provided; these functions are associated with biomembranes and regulated by physical properties of the lipid bilayer such as membrane fluidity, phase transition, and phase separation, as shown in lipid rafts. Other key dynamic aspects of life (cell locomotion, cytoskeletal dynamics, and sensitivities of the cell to physical stimuli such as external forces and temperature) are also discussed. Lastly, readers will learn how life on Earth and its ecological system are maintained by solar energy, and be provided further information on the problems accompanying global warming.
