This Brief provides a comprehensive overview of NMR spectroscopy, covering techniques such as 1H, 13C, and 31P NMR, which are reliable tools to determine lipid oxidation level, to identify oxidation products, and to elucidate oxidation mechanism. The Brief shows that 1H NMR spectroscopy continually demonstrates reliability, accuracy, convenience, and advantages over conventional analytical methods in determination of the level of oxidation of edible oil during frying and storage through monitoring changes in several proton signals of oil, including olefinic, bisallylic and allylic protons. This modern analytical method is shown within this text to be used to identify oxidation products, including primary oxidation products such as hydroperoxides and conjugated dienes and secondary products such as aldehydes, ketones, epoxides and their derivatives. By identifying intermediates and final oxidation products, many oxidation mechanisms could be elucidated. A relatively newer method, the text demonstrates that 13C NMR and 31P NMR spectroscopy can also provide additional information on the molecular structure of an oxidation product. Backgrounds, principles, and advantages over conventional methods, most recent advances, and future prospects of these methods are discussed. Advances in NMR Spectroscopy for Lipid Oxidation Assessment begins by covering the various mechanisms of lipid oxidation, including various methods to determine oxidation products. NMR spectroscopy is then covered, including its applications in foods. The next section focuses on 1H NMR Spectroscopy, including its use for assessment of lipid oxidation during oil storage and frying. The following section focuses on 13C NMR spectroscopy, including its use in determining and identifying oxidation products and mechanisms. A final section focuses on 31P NMR spectroscopy for assessment of lipid oxidation.

This volume brings together information on membrane organization and dynamics from a variety of spectroscopic, microscopic and simulation approaches, spanning a broad range of time scales. The implication of such dynamic information on membrane function in health and disease is a topic of contemporary interest. The chapters cover various aspects of membrane lipid and protein dynamics, explored using a battery of experimental and theoretical approaches. The synthesis of information and knowledge gained by utilizing multiple approaches will provide the reader with a comprehensive understanding of the underlying membrane dynamics and function, which will help to develop robust dynamic models for the understanding of membrane function in healthy and diseased states.   In the last few years, crystal structures of an impressive number of membrane proteins have been reported, thanks to tremendous advances in membrane protein crystallization techniques. Some of these recently solved structures belong to the G protein-coupled receptor (GPCR) family, which are particularly difficult to crystallize due to their intrinsic flexibility. Nonetheless, these static structures do not provide the necessary information to understand the function of membrane proteins in the complex membrane milieu. This volume will address the dynamic nature of membrane proteins within the membrane and will provide the reader with an up-to date overview of the theory and practical approaches that can be used.   This volume will be invaluable to researchers working in a wide range of scientific areas, from biochemistry and molecular biology to biophysics and protein science. Students of these fields will also find this volume very useful. This book will also be of great use to those who are interested in the dynamic nature of biological processes. .
