Lipids m the nervous system are major components of the m- branes. The presence of glycolipids in high concentrations is unique for the nervous system. Recent discoverres of the functronal and pathological importance of lipids such as diacylglycerols, polyphosphoinositides, prostaglandins, leukotrienes, docosahexaenoic acid, platelet activating factor, and gangliosides have markedly increased the number of publications on nervous system lipids. Many new methods have been developed. Thus, there IS a need for this volume that is dedicated to that methodo- gy. This volume places all of the methods for lipids into perspective with recommendations concerning the selection of a method for a specific purpose. Lloyd A.

This book represents the proceedings of a Satellite Symposium of the XIth International Congress of Biochemistry on "Control of Membrane Fluidity" which was held on July 7, 1979 at the Charles H. Best Institute, University of Toronto, Toronto, Canada. The meeting was organized by M. Kates and A. Kuksis and was supported by the International Congress of Biochemistry. The purpose of the meeting was to review recent progress in many different areas of investigation bearing on the role of lipids in the structural and functional property of the cell membrane commonly referred to as fluidity. The aim was to emphasize the factors controlling membrane fluidity as studied in appropriate in vitro and in vivo experiments. The Symposium included invited review papers and short papers offered by discussants. In assem. bling the book no distinction has been made between the two types of presentations, nor has any significance been attached to the chronological order of their presentation in the Symposium. As a result it was possible to provide a much more coherent and continuous presentation than that available at the meeting."

Phospholipid technology and applications is an essential reference for technologists developing food and cosmetics products, scientists researching phospholipids in biological and food systems, technologists in fats and oils refining, and scientists developing drugs and drug delivery systems and carriers.
The major source of phospholipids is the lecithin recovered during degumming of vegetable oils, particularly soybean oil. This crude material finds uses in its own right but can be purified through a series of processes which eventually lead to individual phospholipid classes such as phosphatidylcholines.
It is widely accepted that oil and water do not mix but there are several areas in science and technology where these two distinct phases must coexist in stable emulsions. This is achieved by admixture of amphiphilic molecules of which the phospholipids are important natural examples. Today, phospholipids find many uses in the food industry and in other industries which exploit the amphiphilic nature of these compounds. Further, there are now important procedures by which their amphiphilicity can be optimized for different uses.
The early chapters in this book are devoted to the more common glycerol-based phospholipids and cover their structure, source, composition, modification by chemical and enzymatic methods, their physical, chemical, and nutritional properties, and their major uses. The final chapter is devoted to another kind of phospholipid, the sphingolipids, in which there is a growing interest.

This book provides coverage of all aspects of lipid biochemistry and is intended for undergraduates, although it will also be useful for postgraduates and research workers as a first reference. This fourth edition has been rewritten and restructured to incorporate recent advances and to present a broader range of material. The organization of the content is based on an approach which classifies lipids primarily in terms of their functions in living organisms, rather than according to chemical structure. The first chapters deals with definitions, terminology and chemical classifications, and the second with isolation, separation and detection of lipids. Subsequent chapters, each of which incorporates a brief outline of the lipids, then discuss their biochemistry and functions. A feature of this edition is a more detailed treatment of the nutritional and chemical aspects of lipids. The book takes examples from a wide range of living organisms, including microorganisms and higher plants, as well as animals. The book is illustrated and cross-referenced for the convenience of the reader.

In this second edition, Edwin Frankel has updated and extended his now well-known book Lipid oxidation which has come to be regarded as the standard work on the subject since the publication of the first edition seven years previously. His main objective is to develop the background necessary for a better understanding of what factors should be considered, and what methods and lipid systems should be employed, to achieve suitable evaluation and control of lipid oxidation in complex foods and biological systems.
The oxidation of unsaturated fatty acids is one of the most fundamental reactions in lipid chemistry. When unsaturated lipids are exposed to air, the complex, volatile oxidation compounds that are formed cause rancidity. This decreases the quality of foods that contain natural lipid components as well as foods in which oils are used as ingredients. Furthermore, products of lipid oxidation have been implicated in many vital biological reactions, and evidence has accumulated to show that free radicals and reactive oxygen species participate in tissue injuries and in degenerative disease.
Although there have been many significant advances in this challenging field, many important problems remain unsolved. This second edition of Lipid oxidation follows the example of the first edition in offering a summary of the many unsolved problems that need further research. The need to understand lipid oxidation is greater than ever with the increased interest in long-chain polyunsaturated fatty acids, the reformulation of oils to avoid hydrogenation and trans fatty acids, and the enormous attention given to natural phenolic antioxidants, including flavonoids and other phytochemicals.

In this book, renowned scientists describe how cholesterol interacts with various proteins. Recent progress made in the high-resolution visualization of cholesterol-protein interactions using crystallography and cryogenic electron microscopy has substantially advanced the knowledge of critical features. These features enable specific recognition of the cholesterol molecule by proteins, a process that was built on earlier studies using binding assays, computational modeling and site-directed mutagenesis. Direct Mechanisms in Cholesterol Modulation of Protein Function offers comprehensive insights into the current understanding of cholesterol-driven modulation of protein function via direct sensing. Its nine chapters are organized into two distinct parts. In the first part, the chapters introduce the reader to the general characteristics of cholesterol binding sites in proteins. This part starts with a tour into common cholesterol recognition motifs, followed by an overview of the major classes of steroid-binding proteins. It then continues with two chapters that present a comprehensive analysis of molecular and structural characteristics of cholesterol binding sites in transmembrane and soluble protein domains. In the second part of the book, examples of cholesterol binding sites and consequences of specific cholesterol recognition for protein function are presented for G protein-coupled receptors, ion channels and cholesterol-transporting proteins. The book is valuable for undergraduate and graduate students in biochemistry and nutrition, as well as basic science and medical researchers with a keen interest in the biophysical properties of cholesterol and physiological consequences of cholesterol presence in biological systems.

This detailed book examines experimental approaches used to investigate the regulation and function of phosphoinositides (PtdInsP), rare eukaryotic phospholipids with a broad role in biological processes such as signal transduction, cell migration and adhesion, cell growth, subcellular organization, and membrane trafficking. The combination of complementary biochemical, mass spectrometry, and imaging methods are instrumental for the detection and quantification of PtdInsP species, as well as induced dimerization methods, affinity precipitation or co-sedimentation with liposomes, protein insertion within lipid bilayers, and enzymatic assays, or through emerging methods like native mass spectrometry and microfluidics, all of which are touched upon in this volume. Written in the highly successful Methods in Molecular Biology format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Phosphoinositides: Methods and Protocols provides detailed methodology for both specialist and novice researchers on a variety of complementary methods that have been instrumental in dissecting the regulation, dynamics, and function of PtdInsPs.

In the last decade, research on platelet-activating factor (PAF) has expanded exponentially. Previous conferences on PAF in Paris, 1983, and the subsequent conferences in Gatlinburg, Ten nessee, Tokyo, Snowbird, Utah, and Berlin, at three-yearly intervals, have chronicled the devel opments in the field ofPAF. This volume records the proceedings of the Fifth International Con gress on PAF and Related Lipid Mediators, held at the Free University Medical Hospital Ben jamin Franklin in Berlin, from September 12-16, 1995. We are very much indebted to Free Uni versity Berlin for providing tremendous facilities and financial support. It was a great pleasure to have positive and generous input from the German Science Council (DFG), Bonn, Germany, and British.Biotech, Oxford, United Kingdom. Their support was crucial in making the congress a scientific success. Twenty other organizations provided additional financial support, for which we extend our deepest appreciation. The editors would like to thank all of those who participated in this congress and the authors for their contributions. The organization and planning of the Berlin Congress were carried out by an organizing committee. We gratefully acknowledge the support and assistance of the organizing commit tee members, especially Renate Nigam and Renate Roux for their untiring efforts to make the congress successful. Many colleagues also supported the congress with dedication, hard work, and expert input. We are grateful to them. We also wish to acknowledge the support of G. Sravan Kumar and Louis Kock for their efforts in producing this volume."

This book offers a new physical chemistry perspective on the control of lipid oxidation reactions by antioxidants, and it further explores the application of several oxidation inhibition strategies on food and biological systems. Divided in 3 parts, the book reviews the latest methods to control lipid oxidation, it examines lipid oxidation and inhibition in different food systems, and it finishes with an overview of the biological, health and nutritional effects of lipid oxidation. Chapters from expert contributors cover topics such as the use of magnetic methods to monitor lipid and protein oxidation, the kinetics and mechanisms of lipid oxidation and antioxidant inhibition reactions, interfacial chemistry, oxidative stress and its impact in human health, nutritional, sensory and physiological aspects of lipid oxidation, and new applications of plant and marine antioxidants. While focused on lipid peroxidation in food and biological systems, the chemistry elucidated in this book is applicable also to toxicology, medicine, plant physiology and pathology, and cosmetic industry. The book will therefore appeal to researchers in the lipid oxidation field covering food, biological and medical areas.

Recent advances in our understanding of the fundamental role of bioactive lipids in normal and abnormal physiology was the theme of the XVlth International Spring Sympo- 6-9, 1996 at the George Washington University School sium on Health Sciences held on May of Medicine in Washington, D.C. Over 250 participants shared their latest findings on fundamental mechanisms in lipid metabolism, transport, and signal transduction. Most of the papers presented at the plenary sessions have been collected in this volume, which is divided into seven parts. The focus of Part I is on the new roles that fatty acids and esters play in cellular function. These activities include regulation of gene expression, control of eicosanoid-me- diated responses, and intracellular calcium sequestration. Most biological effects of fatty acids, esters, and phospholipids are transmitted via the interaction of these lipid molecules with specific lipid binding proteins. The chapters in Part II detail the involvement of these in the transport of fatty acids, fatty acyl CoA esters, and phospholipids, and in the proteins modulation of the fatty acid-induced activation of the peroxisome proliferator-activated receptors. The study of arachidonic acid metabolism continues to be the subject of intense interest and research. A number of studies in Part III deal with the substantial differences between the constitutive prostaglandin H synthase isozyme (PGHS-l or COX-I) and the inducible form PGHS-2 (COX-2) regarding compartmentation, control, and expression.

Lipobiology is a rapidly evolving interdisciplinary field which incorporates critical aspects of lipid and lipoprotein chemistry into the disciplines of cell biology and physiology. This series focuses on salient aspects of the role of lipids in metabolic regulation and cellular activation.

Angiogenesis has recently played a critical role in regulation of adipose tissue expansion and regression. Like most other tissues in the body, adipose expansion and regression is accompanied by alteration of blood vessel density and structures. The vascular alteration plays an active role in regulation of adipose tissue size and functions. Targeting blood vessels in the adipose tissue have demonstrated to be a novel approach for possibly treatment of cancer, obesity and other metabolic diseases. This book provides the most updated information on this type research and discusses future opportunities for therapy..

The scientific advances in the physiology and pathophysiology of adipose tissue over the last two decades have been considerable. Today, the cellular and molecular mechanisms of adipogenesis are well known. In addition, adipose tissue is now recognized as a real endocrine organ that produces hormones such as the leptin acting to regulate food intake and energy balance in the central nervous system, a finding that has completely revolutionized the paradigm of energy homeostasis. Other adipokines have now been described and these molecules are taking on increasing importance in physiology and pathophysiology. Moreover, numerous works have shown that in obesity, but also in cases of lipodystophy, adipose tissue was the site of a local low-grade inflammation that involves immune cells such as macrophages and certain populations of lymphocytes. This new information is an important step in the pathophysiology of both obesity and related metabolic and cardiovascular complications. Finally, it is a unique and original work focusing on adipose tissue, covering biology and pathology by investigating aspects of molecular and cellular biology, general, metabolic, genetic and genomic biochemistry.

Biological membranes have long been identified as key elements in a wide variety of cellular processes including cell defense communication, photosynthesis, signal transduction, and motility; thus they emerge as primary targets in both basic and applied research. This book brings together in a single volume the most recent views of experts in the area of proteina "lipid interactions, providing an overview of the advances that have been achieved in the field in recent years, from very basic aspects to specialized technological applications. Topics include the application of X-ray and neutron diffraction, infrared and fluorescence spectroscopy, and high-resolution NMR to the understanding of the specific interactions between lipids and proteins within biological membranes, their structural relationships, and the implications for the biological functions that they mediate. Also covered in this volume are the insertion of proteins and peptides into the membrane and the concomitant formation of definite lipid domains within the membrane.
