Book Synopsis Structure and Dynamics of Membranes by : R. Lipowsky
Download or read book Structure and Dynamics of Membranes written by R. Lipowsky and published by Elsevier. This book was released on 1995-06-15 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first volume of the Handbook deals with the amazing world of biomembranes and lipid bilayers. Part A describes all aspects related to the morphology of these membranes, beginning with the complex architecture of biomembranes, continues with a description of the bizarre morphology of lipid bilayers and concludes with technological applications of these membranes. The first two chapters deal with biomembranes, providing an introduction to the membranes of eucaryotes and a description of the evolution of membranes. The following chapters are concerned with different aspects of lipids including the physical properties of model membranes composed of lipid-protein mixtures, lateralphase separation of lipids and proteins and measurement of lipid-protein bilayer diffusion. Other chapters deal with the flexibility of fluid bilayers, the closure of bilayers into vesicles which attain a large variety of different shapes, and applications of lipid vesicles and liposomes. Part B covers membrane adhesion, membrane fusion and the interaction of biomembranes withpolymer networks such as the cytoskeleton. The first two chapters of this part discuss the generic interactions of membranes from the conceptual point of view. The following two chapters summarize the experimental work on two different bilayer systems. The next chapter deals with the process ofcontact formation, focal bounding and macroscopic contacts between cells. The cytoskeleton within eucaryotic cells consists of a network of relatively stiff filaments of which three different types of filaments have been identified. As explained in the next chapter much has been recently learned aboutthe interaction of these filaments with the cell membrane. The final two chapters deal with membrane fusion.

Book Synopsis Life - As a Matter of Fat by : Ole G. Mouritsen
Download or read book Life - As a Matter of Fat written by Ole G. Mouritsen and published by Springer Science & Business Media. This book was released on 2005-10-24 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents a multi-disciplinary perspective on the physics of life and the particular role played by lipids and the lipid-bilayer component of cell membranes. Emphasizes the physical properties of lipid membranes seen as soft and molecularly structured interfaces. By combining and synthesizing insights obtained from a variety of recent studies, an attempt is made to clarify what membrane structure is and how it can be quantitatively described. Shows how biological function mediated by membranes is controlled by lipid membrane structure and organization on length scales ranging from the size of the individual molecule, across molecular assemblies of proteins and lipid domains in the range of nanometers, to the size of whole cells. Applications of lipids in nano-technology and biomedicine are also described.

Book Synopsis Bilayer Lipid Membranes. Structure and Mechanical Properties by : Tibor Hianik
Download or read book Bilayer Lipid Membranes. Structure and Mechanical Properties written by Tibor Hianik and published by Springer Science & Business Media. This book was released on 1995-08-31 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Bilayer Lipid Membranes. Structure and Mechanical Properties the authors use new methods of measurement, which they have themselves developed, to present an analysis of the relation between membrane structure and viscoelastic properties, in particular in the transversal direction. Hianik and Passechnik's approach is fundamentally different from the usual one, in that they analyze lipid bilayer dynamics during various modes of deformation, arriving at a new, `three-layer' model that accounts for the great heterogeneity of biomembranes. The macroscopic parameters of membranes have been measured using a wide variety of methods, leading to a discussion of the correlations between the parameters. There is also an extensive discussion of the dynamic changes in mechanical properties of lipid bilayers in the course of conformational transition of integral proteins. During the conformational changes of proteins, the structure of a bilayer undergoes a transition, reaching a new, stable membrane state. The book is the first to present a comprehensive analysis of long-distance interaction in lipid bilayers and of molecular mechanisms of mechanoreception. Audience: Scientists and graduate students working in biophysics, membranology, physiology, medicine, pharmacology, bioelectronics, electrochemistry, and colloid chemistry.
Book Synopsis Biological Membranes by : Kenneth M. Merz
Download or read book Biological Membranes written by Kenneth M. Merz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interface between a living cell and the surrounding world plays a critical role in numerous complex biological processes. Sperm/egg fusion, virus/cell fusion, exocytosis, endocytosis, and ion permeation are a few examples of processes involving membranes. In recent years, powerful tools such as X-ray crystal lography, electron microscopy, nuclear magnetic resonance, and infra-red and Raman spectroscopy have been developed to characterize the structure and dy namics of biomembranes. Despite this progress, many of the factors responsible for the function of biomembranes are still not well understood. The membrane is a very complicated supramolecular liquid-crystalline structure that is largely composed of lipids, forming a bilayer, to which proteins and other biomolecules are anchored. Often, the lipid bilayer environment is pictured as a hydropho bic structureless slab providing a thermodynamic driving force to partition the amino acids of a membrane protein according to their solubility. However, much of the molecular complexity of the phospholipid bilayer environment is ignored in such a simplified view. It is likely that the atomic details of the polar head group region and the transition from the bulk water to the hydrophobic core of the membrane are important. An understanding of the factors responsible for the function of biomembranes thus requires a better characterization at the molec ular level of how proteins interact with lipid molecules, of how lipids affect protein structure and of how lipid molecules might regulate protein function.

Book Synopsis The Physical Chemistry of MEMBRANES by : B. Silver
Download or read book The Physical Chemistry of MEMBRANES written by B. Silver and published by Springer. This book was released on 1985-08-31 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Concepts of Membrane Structure by : Ronald Aloia
Download or read book Concepts of Membrane Structure written by Ronald Aloia and published by Elsevier. This book was released on 2012-12-02 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane Fluidity in Biology, Volume 1: Concepts of Membrane Structure covers membrane properties influenced by alterations in membrane lipid compositions and/or other organizational parameters that are encompassed by the term fluidity. This book is composed of eight chapters that discuss significance of fluidity changes in both normal and pathological cellular functions. This book starts by describing membrane structural organization and composition and arrangement of the molecular components of cell membranes. This is followed by discussions on structural properties of lipids and role of nonbilayer lipid structures in membrane fusion. The methodological approaches in study of cellular membrane structural diversity and fluid mosaic model for accurate representation of membrane fluidity are also discussed. This volume then describes the phenomenon of reversed or ""negative"" membrane images, as viewed with transmission electron microscope. Chapters 6 and 7 explain the interaction of cytochrome P-450 with phospholipids and proteins in the endoplasmic reticulum and steps in the derivation of membrane structure and packing principles. Finally, the concluding chapter focuses on the membrane of the human red blood cell and presents relatively simple arguments concerning its physical properties. The book will serve as a primary source for research scientists and teachers interested in cellular membrane fluidity phenomena.

Book Synopsis Membrane Hydration by : E. Anibal Disalvo
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 295 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.
