Download or read book Thermal Biophysics of Membranes written by Thomas Heimburg and published by John Wiley & Sons. This book was released on 2008-02-08 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

The main sections are: (1) Basic principles of equilibrium thermodynamics. (2) Structure and behavior of solutions of ions and molecules. The discussions range from properties of bulk water to the solvent structure of solutions of small molecules and macromolecules. (3) Physical principles are extended for the non-homogenous and non-equilibrium nature of biological processes. Areas included are lipid/water systems, transport phenomena, membranes, and bio-electrochemistry. This new textbook will provide an essential foundation for research in cellular physiology, biochemistry, membrane biology, as well as the derived areas bioengineering, pharmacology, nephrology, and many others.

Download or read book The Biophysics of Cell Membranes written by Richard M. Epand and published by Springer. This book was released on 2017-09-25 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the modulation of biological membranes by specific biophysical properties. The readers are introduced to emerging biophysical approaches that mimick specific states (like membrane lipid asymmetry, membrane curvature, lipid flip-flop, lipid phase separation) that are relevant to the functioning of biological membranes. The first chapter describes innovative methods to mimic the prevailing asymmetry in biological membranes by forming asymmetrical membranes made of monolayers with different compositions. One of the chapters illustrates how physical parameters, like curvature and elasticity, can affect and modulate the interactions between lipids and proteins. This volume also describes the sensitivity of certain ion channels to mechanical forces and it presents an analysis of how cell shape is determined by both the cytoskeleton and the lipid domains in the membrane. The last chapter provides evidence that liposomes can be used as a minimal cellular model to reconstitute processes related to the origin of life. Each topic covered in this volume is presented by leading experts in the field who are able to present clear, authoritative and up-to-date reviews. The novelty of the methods proposed and their potential for a deeper molecular description of membrane functioning are particularly relevant experts in the areas of biochemistry, biophysics and cell biology, while also presenting clear and thorough introductions, making the material suitable for students in these fields as well.
Download or read book Methods in Membrane Biology written by Edward D. Korn and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contributions of electron microscopy to membrane biology have been indispensable and, at the same time, disappointing. Membranes were known to exist before the advent of electron microscopy and general principles of their composition and molecular organization had been deduced from permeability and electrical conductivity measurements, polarized light microscopy, and X-ray diffraction. On the other hand, the complexities of the many intracellular membranes and membranous organelles were really not suspected until they were observed by the electron microscopist. One then had further hopes that the high resolution of the electron microscope (theoretically it can resolve atomic distances) would allow the visualization of the molecular architecture of membranes and lead directly to an under standing of structure and function at the molecular level. This expectation has been largely unrealized. Because of the great difficulties encountered in the preparation of biological material, because of the uncertainty of the chemistry of "staining," and because of numerous electron optical artifacts, it has been a major challenge just to rationalize the observed images in terms of the known facts, let alone to utilize the images to expand our knowledge of the molecular structure of biological membranes. The many differences among membranes with respect to function and composition are lost in the universal trilamellar image. Perhaps the one major exception to this, and the major structural contribution of electron microscopy at the molecular level, has come from freeze-etch electron microscopy.
Download or read book Physics of Biological Membranes written by Patricia Bassereau and published by Springer. This book was released on 2018-12-30 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Thermodynamics of Membrane Receptors and Channels written by Meyer B. Jackson and published by CRC Press. This book was released on 1992-11-18 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book An Introduction to Biological Membranes written by William Stillwell and published by Elsevier. This book was released on 2016-06-30 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Biological Membranes: Composition, Structure and Function, Second Edition is a greatly expanded revision of the first edition that integrates many aspects of complex biological membrane functions with their composition and structure. A single membrane is composed of hundreds of proteins and thousands of lipids, all in constant flux. Every aspect of membrane structural studies involves parameters that are very small and fast. Both size and time ranges are so vast that multiple instrumentations must be employed, often simultaneously. As a result, a variety of highly specialized and esoteric biochemical and biophysical methodologies are often utilized. This book addresses the salient features of membranes at the molecular level, offering cohesive, foundational information for advanced undergraduate students, graduate students, biochemists, and membranologists who seek a broad overview of membrane science. Significantly expanded coverage on function, composition, and structure Brings together complex aspects of membrane research in a universally understandable manner Features profiles of membrane pioneers detailing how contemporary studies originated Includes a timeline of important discoveries related to membrane science
Download or read book Membrane Transport written by Arnost Kotyk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not many years ago, problems of membranes and transport attracted the attention of but a few dozen enthusiasts, mainly physiolo gists who recognize~ the significance of membranes for the stabilization of the general steady state of organisms. The first symposium organ ized some fifteen years ago could boast of the attendance of perhaps fifty scientists (the remaining fifty were not yet sure that membranes was the topic of their choice), ranging in specialization from physical chemistry to bacterial genetics, who clairvoyantly decided to study what now has become the number one subject at most congresses of biophysics, physiology, and even biochemistry and microbiology. As is the case with many rapidly developing fields, the interest in membranes and transport seems to be growing out of bounds and the whole field of membra no logy, interdisciplinary as it is, has penetrated into the realms of a number of branches of physics, chemistry, and biology. Its subject is primarily biological and, although much has been done in the world to increase the "exactness" of biology over the past thirty years, one cannot strive for a rigorous mathematical description of biological phenomena since, as M.

Download or read book Smart Membranes and Sensors written by Annarosa Gugliuzza and published by John Wiley & Sons. This book was released on 2014-09-19 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the reader to use synergistically the concepts of membranes and sensors materials. It contains insightful contributions from leading scientists working in both the fields. The focus is on the fabrication of smart membranes from sensor materials and related impact on many technologically sophisticated areas such as telemedicine, microfluidics, drug delivery targeting, (bio)separation, labs-on-a-chip, textiles, power storage and release, environment monitoring, agro-food safety, cosmetics, architecture, automotive and so on. This book covers various topics, including the choice of materials and techniques for assembling responsive membranes with ability to transport mass, energy and signals on demand; the reader will find through the book an extensive description of the best techniques used to monitor molecular scale events, which are regarded as responsible for the smartness of multifunctional objects and for the conversion of chemical signals into optical, electrical, thermal and mechanical responses. The reader is encouraged to use this cross-disciplinary discussion for his own research. Chemical, biological and physical concepts, expressed through the book, contribute to form a common language, which will allow the reader to discover causes for reflection and innovation, measuring how smart objects with desired properties can be tailored from exiting materials and used flexibly for different developed applications. Specifically: This book deals with materials smartness and suitable techniques to assemble and characterize them in sensor-like membranes. This book shows how ultra-smart functional devices can be accomplished by using traditional raw materials. This book describes particular key events, which control 'sense to react and adapt' mechanisms. The potential of sensor-like membranes in some key strategic fields is examined with particular emphasis on biomedicine, food and textiles markets. The benefits arising from the use of smart membranes are analysed in terms of life quality, safety, and innovation.
Download or read book Membrane Hydration written by E. Anibal Disalvo and published by Springer. This book was released on 2015-10-05 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the importance of water in determining the structure, stability and responsive behavior of biological membranes. Water confers to lipid membranes unique features in terms of surface and mechanical properties. The analysis of the hydration forces, plasticiser effects, controlled hydration, formation of microdomains of confined water suggests that water is an active constituent in a water-lipid system. The chapters describe water organization at the lipid membrane–water interphase, the water penetration, the long range water structure in the presence of lipid membranes by means of X-ray and neutron scattering, general polarization, fluorescent probes, ATR-FTIR and near infrared spectroscopies, piezo electric methods, computer simulation and surface thermodynamics. Permeation, percolation, osmotic stress, polarization, protrusion, sorption, hydrophobicity, density fluctuations are treated in detail in self-assembled bilayers. Studies in lipid monolayers show the correlation of surface pressure with water activity and its role in peptide and enzyme interactions. The book concludes with a discussion on anhydrobiosis and the effect of water replacement in microdomains and its consequence for cell function. New definitions of lipid/water interphases consider water not only as a structural-making solvent but as a mediator in signalling metabolic activity, modulating protein insertion and enzymatic activity, triggering oscillatory reactions and functioning of membrane bound receptors. Since these effects occur at the molecular level, membrane hydration appears fundamental to understand the behavior of nano systems and confined environments mimicking biological systems. These insights in structural, thermodynamical and mechanical water properties give a base for new paradigms in membrane structure and function for those interested in biophysics, physical chemistry, biology, bio and nano medicine, biochemistry, biotechnology and nano sciences searching for biotechnological inputs in human health, food industry, plant growing and energy conversion.
