Book Description
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 Description
Biological membranes are the essential structuring elements of all living cells. Many enzymatic reactions take place at the membrane-water interface. To gain detailed insight into membrane properties, it is therefore of great importance to understand the complex nature of the interactions of membrane proteins with lipids. Lipid-Protein Interactions: Methods and Protocols provides a selection of protocols to examine protein-lipid interactions, membrane and membrane protein structure, how membrane proteins affect lipids and how they are in turn affected by the lipid bilayer and lipid properties. The methods described here are all actively used, complementary, and necessary to obtain comprehensive information about membrane structure and function. They include label-free approaches, imaging techniques and spectroscopic methodologies. Written in the successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Lipid-Protein Interactions: Methods and Protocols seeks to serve both professional and novices with its wide range of the methods frequently used in this area of research.

Book Description
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 Description
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 Description
This book presents a comprehensive and coherent picture of how molecules diffuse across a liquid that is, on average, only two molecules thick. It begins by characterizing bilayers structurally, using X-ray diffraction, and then mechanically by measuring elastic moduli and mechanisms of failure. Emphasis is placed on the stability and mechanical properties of plant membranes that are subject to very large osmotic and thermal stresses. Using this information, the transport of molecules of increasing complexity across bilayers is analyzed.

Book Description
Although not the only volume in this series in which lipids are discussed, the present volume is devoted entirely to methods for the study of membrane lipids. Even now, when membrane proteins are properly receiving so much attention, this emphasis on membrane lipids is appropriate. Essentially all of the phospholipids and sterols of cells are in membranes. Moreover, although membrane proteins are certainly of utmost importance, the more we learn about the functional properties of membrane proteins, the more we appreciate the unique features of phospholipids, without which biological membranes would be impossible. The hydrophobic-hydrophilic duality of phospholipids allows, indeed requires, their association, in an aqueous environment, into an essentially two-dimensional membrane-only molec ularly thick in one dimension but relatively infinite in the other two; a structure composed of small molecules, not covalently linked, and therefore, infinitely mobile and variable, but yet a structure with great stability and one largely impermeable to most biomolecules. These membrane-forming properties are shared by many amphipathic polar lipids-phospholipids, glycolipids, and sphingolipids-that differ significantly from each other in the nature of their polar head groups and their fatty acids. These variations in structure allow a range of specific interactions among membrane lipids and between lipids and proteins and also provide for membranes of variable, but controlled, fluidity. In this way, phospholipids provide an appropriate milieu for functional membrane proteins and also significantly modulate their catalytic activities.
