Biophysical Approaches for the Study of Membrane Structure, Part B, Volume 701 explores lipid membrane asymmetry and lateral heterogeneity. A burst of recent research has shown that bilayers whose leaflets differ in their physical properties—such as composition, phase state, or lateral stress—exhibit many fascinating new characteristics, but also pose a host of challenges related to their creation, characterization, simulation, and theoretical description. Chapters in this new release include Characterization of domain formation in complex membranes: Analyzing the bending modulus from simulations of complex membranes, The density-threshold affinity: Calculating lipid binding affinities from unbiased Coarse-Grain Molecular Dynamics simulations, and much more. Additional sections cover Uncertainty quantification for trans-membrane stresses and moments from simulation, Using molecular dynamics simulations to generate small-angle scattering curves and cryo-EM images of proteoliposomes, Binary Bilayer Simulations for Partitioning Within Membranes, Modeling Asymmetric Cell Membranes at All-atom Resolution, Multiscale remodeling of biomembranes and vesicles, Building complex membranes with Martini 3, Predicting lipid sorting in curved bilayer membranes, Simulating asymmetric membranes using P21 periodic boundary conditions, and many other interesting topics. Explore the state-of-the-art of lipid membrane asymmetry Covers experimental, theoretical, and computational techniques to create and characterize asymmetric lipid membranes Teaches how these kinds of approaches create and characterize laterally inhomogeneous membranes

The plasma membrane is at once the window through which the cell senses the environment and the portal through which the environment influences the structure and activities of the cell. Its importance in cellular physiology can thus hardly be overestimated, since constant flow of materials between cell and environment is essential to the well-being of any biological system. The nature of the materials mov ing into the cell is also critical, since some substances are required for maintenance and growth, while others, because of their toxicity, must either be rigorously excluded or permitted to enter only after chemical alteration. Such alteration frequently permits the compounds to be sequestered in special cellular compartments having different types of membranes. This type of homogeneity, plus the fact that the wear and tear of transmembrane molecular traffic compels the system to be constantly monitored and repaired, means that the membrane system of any organism must be both structurally complex and dy namic. Membranes have been traditionally difficult to study because of their fragility and small diameter. In the last several decades, however, remarkable advances have been made because of techniques permit ting the bulk isolation of membranes from homogenized cells. From such isolated membranes have come detailed physical and chemical analyses that have given us a detailed working model of membrane. We now can make intelligent guesses about the structural and func tional interactions of membrane lipids, phospholipids, proteins, sterols and water.

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.
