Probes and Membrane Function PDF Author: Britton Chance
Publisher: Academic Press
ISBN: 148327148X
Category : Science
Languages : en
Pages : 582

Book Description
Probes of Structure and Function of Macromolecules and Membranes, Volume I: Probes and Membrane Function discusses the developments in techniques for the measurement of rapid reactions and detection of enzymatic reactions in simple and complex systems. This book describes the application of the incisive techniques employed for the study of activity-related structural changes in enzymes to functionally related structural changes in membranes. The structural changes initiated in response to energy coupling and ion movements in mitochondria and axons are also elaborated. This publication covers the basic mechanisms by which structural changes can participate in energy coupling at the redox level of the hemoproteins that leads to the evaluation of the function of ubiquinone and cytochrome b in energy coupling. The function of factors that couple electron transport and energy conservation is likewise considered. This volume is a good reference for students and researchers conducting work on the structure and function of macromolecules and membranes.

Membrane Hydration

Membrane Hydration PDF Author: E. Anibal Disalvo
Publisher: Springer
ISBN: 3319190601
Category : Science
Languages : en
Pages : 295

Book Description
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.

Mesoscale Chemistry

Mesoscale Chemistry PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 030937331X
Category : Science
Languages : en
Pages : 229

Book Description
In the last few decades great strides have been made in chemistry at the nanoscale, where the atomic granularity of matter and the exact positions of individual atoms are key determinants of structure and dynamics. Less attention, however, has been paid to the mesoscale-it is at this scale, in the range extending from large molecules (10 nm) through viruses to eukaryotic cells (10 microns), where interesting ensemble effects and the functionality that is critical to macroscopic phenomenon begins to manifest itself and cannot be described by laws on the scale of atoms and molecules alone. To further explore how knowledge about mesoscale phenomena can impact chemical research and development activities and vice versa, the Chemical Sciences Roundtable of the National Research Council convened a workshop on mesoscale chemistry in November 2014. With a focus on the research on chemical phenomena at the mesoscale, participants examined the opportunities that utilizing those behaviors can have for developing new catalysts, adding new functionality to materials, and increasing our understanding of biological and interfacial systems. The workshop also highlighted some of the challenges for analysis and description of mesoscale structures. This report summarizes the presentations and discussion of the workshop.

Membrane Dynamics and Domains

Membrane Dynamics and Domains PDF Author: Peter J. Quinn
Publisher: Springer Science & Business Media
ISBN: 9780306484254
Category : Science
Languages : en
Pages : 528

Book Description
The fluid-mosaic model of membrane structure formulated by Singer and Nicolson in the early 1970s has proven to be a durable concept in terms of the principles governing the organization of the constituent lipids and proteins. During the past 30 or so years a great deal of information has accumulated on the composition of various cell membranes and how this is related to the dif ferent functions that membranes perform. Nevertheless, the task of explaining particular functions at the molecular level has been hampered by lack of struc tural detail at the atomic level. The reason for this is primarily the difficulty of crystallizing membrane proteins which require strategies that differ from those used to crystallize soluble proteins. The unique exception is bacteriorhodopsin of the purple membrane of Halobacterium halobium which is interpolated into a membrane that is neither fluid nor in a mosaic configuration. To date only 50 or so membrane proteins have been characterised to atomic resolution by diffraction methods, in contrast to the vast data accumulated on soluble proteins. Another factor that has been difficult to explain is the reason why the lipid compliment of membranes is often extremely complex. Many hundreds of different molecular species of lipid can be identified in some membranes. Remarkably, the particular composition of each membrane appears to be main tained within relatively narrow limits and its identity distinguished from other morphologically-distinct membranes.

Calcium Entry Channels in Non-Excitable Cells

Calcium Entry Channels in Non-Excitable Cells PDF Author: Juliusz Ashot Kozak
Publisher: CRC Press
ISBN: 149875273X
Category : Science
Languages : en
Pages : 343

Book Description
Calcium Entry Channels in Non-Excitable Cells focuses on methods of investigating the structure and function of non-voltage gated calcium channels. Each chapter presents important discoveries in calcium entry pathways, specifically dealing with the molecular identification of store-operated calcium channels which were reviewed by earlier volumes in the Methods in Signal Transduction series. Crystallographic and pharmacological approaches to the study of calcium channels of epithelial cells are also discussed. Calcium ion is a messenger in most cell types. Whereas voltage gated calcium channels have been studied extensively, the non-voltage gated calcium entry channel genes have only been identified relatively recently. The book will fill this important niche.
