Provides the reader with an up to date insight of the current state of the art in the field of lipid bilayer research and the important insights derived for the understanding of the complex and varied behaviour of biological membranes and its function.

Free energy constitutes the most important thermodynamic quantity to understand how chemical species recognize each other, associate or react. Examples of problems in which knowledge of the underlying free energy behaviour is required, include conformational equilibria and molecular association, partitioning between immiscible liquids, receptor-drug interaction, protein-protein and protein-DNA association, and protein stability. This volume sets out to present a coherent and comprehensive account of the concepts that underlie different approaches devised for the determination of free energies. The reader will gain the necessary insight into the theoretical and computational foundations of the subject and will be presented with relevant applications from molecular-level modelling and simulations of chemical and biological systems. Both formally accurate and approximate methods are covered using both classical and quantum mechanical descriptions. A central theme of the book is that the wide variety of free energy calculation techniques available today can be understood as different implementations of a few basic principles. The book is aimed at a broad readership of graduate students and researchers having a background in chemistry, physics, engineering and physical biology.

A multidisciplinary resource, Food Proteins and Peptides: Chemistry, Functionality, Interactions, and Commercialization enables researchers in biochemistry, biotechnology, food science and technology, nutrition, and medicine to understand the physicochemical and biochemical factors that govern the functionality of these food components. Following chapters on the structure and chemistry of amino acids, peptides, and proteins, the book describes modes of characterization and the functional relationships of food proteins. It examines protein solubility and insolubility and explores proteins and peptides as emulsifying and foaming agents. Specialized topics include: Factors affecting heat-induced casein–whey protein interactions in bovine milk systems The effects of protein–saccharide interactions on the properties of food components Ameliorative action of peptides on cholesterol and lipid metabolism Proteins and peptides with elements of sweetness, kokumi, umami, and bitterness A new approach for the large-scale fractionation of peptides based on their amphoteric nature The book examines the source of bioactive peptides and describes their bioavailability, including their absorption and occurrence in human blood. It also provides a database of biologically active proteins and peptides. Final chapters review current status, future industrial perspectives, and future trends of bioactive food proteins and peptides and explore the role of nanotechnology in protein research. With contributions from a panel of international scientists, this volume captures the state of the art in protein and peptide research, providing a launching pad for further inquiry and discovery.
