A turning point seems to have been reached recently in our understanding of biological systems. After about 1930, when it became possible to examine the dynamic aspects of a cell seriously and to increase the breadth of our knowledge of the chemicals which are involved, there was a feeling that the elucidation of a pathway or the use to which a compound or a process was put biologically had a ubiquitous character. Among the reasons for believing this was the constancy of the amino acid building blocks for proteins. Not only were the same general structures found regardless of organismic type, but the stereochemistry was the same. This sort of observation led to the idea of the "unity of nature. " Few people, of course, thought a complete unity existed, because it was already known in the latter part of the nineteenth century that the sterols, the polysaccharides, and the pigments of various organisms could be substantially different, but only recently, during the last decade or so, has the fuH scope ofthe difference-as weil as ofthe similarity-begun to emerge. Of particular importance, it has now become evident that a large hiatus exists between some types of organism. Even more important, perhaps, and certainly more unexpected, are the substantial gaps which have been discovered within otherwise similar organisms. The evolutionary process is presumably behind what we observe, and therefore an understanding of the rules and regulations which govern similarity and difference should eventually lead to an elucidation of evolution itself.

This book is about the various roles of bioactive ceramides and other sphingolipids in cellular biology. The enigmatic biophysical and biochemical properties of ceramides and their propensity to influence membranes whether as rafts or protein-permeable channels are heavily discussed. Metabolism of ceramides and their metabolites is also focused with ceramide synthase family of proteins being a target of extensive review. Ceramide 1-phosphate and other sphingolipids are also presented in cellular physiology and pathophysiology. Prokaryotic origins of mitochondria at the level of membranes and the occurrence of apoptosis in bacteria are presented. Many aspects of ceramide and sphingolipid biology are addressed in this book. Its focus is the metabolism of ceramide in normal and diseased states and the biophysical and biochemical mechanisms governing the bioactivity of these molecules. Sphingolipid research has surged over the past thirty years and this book gathers the recent findings of various aspects of sphingolipid biochemistry. World-renowned scientists from the field of lipid biology, specifically sphingolipid biochemistry, were gathered to write this book. Scholars from most continents of the globe committed to write diligently about their expertise and the newest findings in the relevant fields. This book came to fruition after almost a year and a half of laborious preparation and diligent writings. This book is targeted to the experienced reader who is looking to read about the various aspects of bioactive ceramide signaling, as well as to the newcomer into the field, as the topics are explained in concise yet very informative manner. The authors and editor wish all readers a pleasant time reading this volume, and are adamant that this book will meet all expectations.

This handbook provides a comprehensive overview of lipid membrane fundamentals and applications. It gives the fundamental physical and biochemical aspects of membrane-related processes in living cells, and then relates them to how scientists are building bioinspired, artifical membrane-based systems such as gene delivery vehicles and synthetic membrane interfaces. It highlights the driving mechanism behind lipid self-assembly, membrane shape evolution, and vesicle trafficing, as well as the role of lipid membrane composition in signalling and the structural aspects of membranes in cellular integrity. Key Features: Includes a broad overview on the role of lipids as structural components of membranes, energy storage molecules, and signaling molecules. Covers lipids in signaling and the role of lipids in everyday life, from diet and health to cosmetics and pharmaceuticals. Discusses applications in nanotechnology and biomedicine, including liposomes in drug discovery, lipids for in vivo therapeutics, lipid-based sensors, artificial biointerfaces, and synthetic polymers. Includes an exciting section that explores the practical use of Archae lipids, lipids and the origins of life, and future outlook for the field. This book is a great companion for professionals in physics, biochemistry, physical chemistry and material sciences.

Biochemistry of Lipids: Lipoproteins and Membranes, Volume Six, contains concise chapters that cover a wide spectrum of topics in the field of lipid biochemistry and cell biology. It provides an important bridge between broad-based biochemistry textbooks and more technical research publications, offering cohesive, foundational information. It is a valuable tool for advanced graduate students and researchers who are interested in exploring lipid biology in more detail, and includes overviews of lipid biology in both prokaryotes and eukaryotes, while also providing fundamental background on the subsequent descriptions of fatty acid synthesis, desaturation and elongation, and the pathways that lead the synthesis of complex phospholipids, sphingolipids, and their structural variants. Also covered are sections on how bioactive lipids are involved in cell signaling with an emphasis on disease implications and pathological consequences. Serves as a general reference book for scientists studying lipids, lipoproteins and membranes and as an advanced and up-to-date textbook for teachers and students who are familiar with the basic concepts of lipid biochemistry References from current literature will be included in each chapter to facilitate more in-depth study Key concepts are supported by figures and models to improve reader understanding Chapters provide historical perspective and current analysis of each topic

Les substances lipidiques ont longtemps été négligées par les physiologistes, mais des recherches épidémiologiques les ont récemment portées sur le devant de la scène, notamment au travers de leur intérêt dans les domaines de la nutrition et surtout de la santé chez l’Homme. Outre leur importance énergétique, les lipides interviennent dans de nombreux mécanismes cellulaires dont les dérèglements peuvent conduire à des pathologies parfois graves. En effet, en plus de leur impact sur les maladies métaboliques, les systèmes cardiovasculaire et immunitaire et les processus de cancérisation, le système nerveux central peut lui aussi être altéré à des degrés divers par une carence ou un déséquilibre entre les constituants lipidiques ingérés. Après quelques rappels historiques sur la découverte des lipides et leur utilisation, une première partie décrit les principaux lipides présents dans notre ration alimentaire. Puis, les besoins avérés ou éventuels de l’Homme en divers acides gras, stérols et vitamines appartenant au groupe des lipides, sont passés en revue. Enfin, l’impact des principaux lipides sur des pathologies naguère encore peu explorées sous cet aspect est exposé en détail. Les lipides – Nutrition et santé présente, de façon synthétique, un très large panorama de toutes les facettes des lipides, des acides gras aux corps gras les moins abondants, mais tout aussi importants pour l’équilibre de notre organisme. Il permet aux spécialistes de revisiter les principales sources de lipides présentes dans notre alimentation en insistant sur leur production et leur composition. Cet ouvrage s’adresse aux chercheurs, médecins généralistes et spécialistes, diététiciens et étudiants évoluant dans de nombreux domaines tels que la biologie cellulaire, la nutrition ou encore la pharmacologie.
