The book offers graduate students and researchers a coherent overview of lipid transfer and transport, as well as the limitations of current research in the field, and promotes further studies on cardiovascular diseases, as well as pharmaceutical research on drug discovery based on lipid transfer, transport, and binding.

The new series "Microbiology Monographs" begins with two volumes on intracellular components in prokaryotes. In this first volume, "Inclusions in Prokaryotes", the components, labeled inclusions, are defined as discrete bodies resulting from synthesis of a metabolic product. Research on the biosynthesis and reutilization of the accumulated materials is still in progress, and interest in the inclusions is growing. This comprehensive volume provides historical background and comprehensive reviews of eight well-known prokaryotic inclusions.

Obesity and diabetes develop as a complex result of genetic, metabolic and environmental factors and are characterized by increased lipogenesis and lipid accumulation in many tissues. Stearoyl-CoA desaturase (SCD) genes are a critical regulator of lipogenesis and catalyzes the synthesis of monounsaturated fatty acids (MUFA), mainly oleoyl- (18:1n9) and palmitoleoyl-CoA (16:1n7). These MUFAs are the major fatty acid substrates for the synthesis of triglycerides, cholesterol esters, wax esters and membrane phospholipids. There are 4 SCD isoforms (SCD1-4) in mice and two (hSCD1 and hSCD5) expressed in humans. At first glance, stearoyl-CoA desaturase enzyme would be considered a housekeeping enzyme because it synthesizes oleate a well-known fatty acid that is abundant in many dietary sources. However numerous studies have shown that SCD is a very highly regulated enzyme that features in so many physiological processes ranging from fat differentiation, carbohydrate and fat metabolism, inflammation and cancer. The editor's studies using stearoyl-CoA desaturase knockout (SCD1-/-) mice and studies of other investigators using pharmacological approaches to reduce SCD1 expression in mouse tissues have all established that the expression of SCD1 gene isoform represents a key step in partitioning of lipids between storage and oxidation. High SCD expression favors fat storage leading to obesity while reduced SCD expression favors fat burning and leanness. Although these studies clearly illustrated that SCD1 expression is involved in the development of obesity and insulin resistance, questions remain in the elucidation of the mechanisms involved and role of SCD1. This book includes chapters by leading researchers on SCD Genes in the brain, heart, muscle, liver metabolism, Colitis, and more.

Isoprenoids are important in primary and secondary metabolism. They have implications in a myriad of physiological processes notably in plants, microorganisms and parasites, and biological activities at the cellular, organism, and ecosystem levels. The importance of isoprenoids in various areas of the scientific world has spurred intense research worldwide. Also their role in "nutraceuticals" has stimulated scientific curiosity. Literature on isoprenoids is widely scattered in journals with quite differing readerships and geographic distribution. A comprehensive book on isoprenoids does not exist. Isoprenoid Synthesis in Plants and Microorganisms: New Concepts and Experimental Approaches fills this gap by presenting the latest and the most applicable information on isoprenoids. The most recent TERPNET conference serves as the backdrop and provides much of the inspiration for the topics covered in the book. Additional topics of interest are covered as well, making Isoprenoid Synthesis in Plants and Microorganisms: New Concepts and Experimental Approaches the most comprehensive review of isoprenoid synthesis to date.

Biological membranes are the essential structuring elements of all living cells. Many enzymatic reactions take place at the membrane-water interface. To gain detailed insight into membrane properties, it is therefore of great importance to understand the complex nature of the interactions of membrane proteins with lipids. Lipid-Protein Interactions: Methods and Protocols provides a selection of protocols to examine protein-lipid interactions, membrane and membrane protein structure, how membrane proteins affect lipids and how they are in turn affected by the lipid bilayer and lipid properties. The methods described here are all actively used, complementary, and necessary to obtain comprehensive information about membrane structure and function. They include label-free approaches, imaging techniques and spectroscopic methodologies. Written in the successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Lipid-Protein Interactions: Methods and Protocols seeks to serve both professional and novices with its wide range of the methods frequently used in this area of research.

This detailed book provides technical approaches to tackle a variety of questions related to intracellular lipid transport in order to improve our understanding at different scales of how lipids are accurately displaced between organelles, across long distances or at membrane contact sites, or within cellular membranes. The volume begins with methodologies to measure the movement of varied lipid species between or in organelle membranes, inside eukaryotic cells, including plant cells, or in bacteria, and continues in vitro or in silico approaches aiming to define, more from a biochemical and structural standpoints, how lipid transfer proteins (LTPs) or flippases/scramblases precisely function. Written for the highly successful Methods in Molecular Biology series, 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.

Themulticomponentnatureofbiologicalmembranesandtheirintra- andextracel- lar interactions make direct investigations on the membrane structure and processes nearly impossible. Clearly, a better understanding of the membrane properties and the mechanisms determining membrane protein functions is crucial to the imp- mentation of biosensors, bioreactors and novel platforms for medical therapy. For this reason, the interest in model systems suitable for the construction and study of complex lipid/protein membrane architectures has increased steadily over the years. The classical portfolio of model membranes used for biophysical and - terfacial studies of lipid (bi)layers and lipid/protein composites includes Langmuir monolayers assembled at the water/air interface, (uni- and multi-lamellar) vesicles in bulk (liposomal) dispersion, bimolecular lipid membranes (BLMs), and various types of solid-supported membranes. All these have speci?c advantages but also suffer from serious drawbacksthat limit their technical applications. Polymer m- branes comprised of entirely synthetic or hybrid (synthetic polymer/biopolymer) block copolymersappeared to be an attractive alternative to the lipid-based models. Generally, the synthetic block copolymer membranes are thicker and more stable and the versatility of polymer chemistry allows the adoption of relevant properties for a wide range of applications. This volume provides a vast overview of the physico-chemical and synthetic - pectsofarti?cial membranes. Numerousmembranemodelsaredescribed,including their properties(i. e. swelling, drying,lateral mobility,stability, electrical conduct- ity, etc. ), advantages, and drawbacks. The potential applications of these models are discussed and supported by real examples. Chapter 1 summarizesmethodsfor the stabilizationof arti?cial lipid membranes.

Fatty acids play an important role in the barrier function of skin and represent a major source of proinflammatory mediators such as prostaglandins, leukotrienes and other lipids in inflammatory skin disorders. This book combines the two major functions of fatty acids in skin biology. In the first part the biosynthesis of fatty acids in skin with its role in barrier function as well as the role of dietary fatty acids on skin cell function and in the treatment of inflammatory skin diseases is presented. The second part deals with skin as a source of proinflammatory eicosanoids, especially with the keratinocyte as a major cellular source. Metabolism of eicosanoids in skin, its role in psoriasis and atopic dermatitis as well as pharmacological inhibition of eicosanoid biosynthesis is reviewed. The book finishes with a chapter describing the methods used for quantification of fatty acids and derivatives in skin inflammation. Anyone interested in skin physiology would benefit from the overviews about the two sites of fatty acids' function in skin integrity and in skin inflammation.

Lipids in Photosynthesis: Essential and Regulatory Functions, provides an essential summary of an exciting decade of research on relationships between lipids and photosynthesis.

The topics covered include the structure, molecular organization and biosynthesis of fatty acids, glycerolipids and nonglycerolipids in plants, algae, lichens, mosses, and cyanobacteria, as well as in chloroplasts and mitochondria. Several chapters deal with the manipulation of the extent of unsaturation of fatty acids and the effects of such manipulation on photosynthesis and responses to various forms of stress. The final chapters focus on lipid trafficking, signaling and advanced analytical techniques. Ten years ago, Siegenthaler and Murata edited "Lipids in Photosynthesis: Structure, Function and Genetics," which became a classic in the field. "Lipids in Photosynthesis: Essential and Regulatory Functions," belongs, with its predecessor, in every plant and microbiological researcher's bookcase.

This volume represents a collection of contributions from the 6th International Conference on Eicosanoids and Other Bioactive Lipids in Cancer, Inflammation, and Related Diseases held in Boston from September 12-15, 1999. The mission of this meeting was to bring together senior and junior investigators to both announce and examine their recent advancements in cutting-edge research on the roles and actions of lipid mediators and their impact in human physiology and disease pathogenesis. The meeting focused on new concepts in these areas of interest to both clinicians and researchers. The program included several outstanding plenary lectures and presentations by leading experts in the fields of cancer and inflammation. In addition, the Boston meeting presented three Young Investigator awards, one in each of the major focus areas. The meeting was exciting and proved to be very memorable. The program was developed with an emphasis on recent advances in molecular and of lipid mediators relevant in cellular mechanisims involved in the formation and actions inflammation and cancer. Plenary lectures were presented by Prof. Bengt Sammuelsson (Karolinska Institute, Stockholm; 1982 Nobel Laureate in Physiology or Medicine) and Prof. E. 1. Corey (Harvard University; 1990 Nobel Laureate in Chemistry). Both of these plenary lectures were held on Day 1, which set an exciting tone for this meeting. Immediately following these plenary lectures, three simultaneous breakout sessions were held, one of inflammation, a second on cancer and synthesis of novel inhibitors, and a third on enzymes-lipoxygenases/cyclooxygenases and inhibitors.

Lipids and Skin Health is the first effort to summarize and review the studies, ideas, and research that link lipid metabolism to the largest organ of our body, the skin. The book covers the fundamental biology of the skin, and the major involvement of the transcriptional factors that govern lipid synthesis and the bioactive lipids in this intriguing organ. All layers of skin are presented, as well as their relevant lipids from the epidermis to dermis and even to the hypodermis. The important and unique-to-skin biological pathways are laid out, with a special focus on the various models that demonstrate the essential role of lipid synthesis in skin pathophysiology. The use of lipids in the cosmetic industry is emphasized, and last but not least the involvement of lipids in the clinical setting is also discussed. This book will appeal to healthcare professionals, researchers and dermatology professionals, and will help them to brainstorm new products and opportunities that will target the emerging importance of lipid metabolism in skin for acne, aging, and healthy skin. Apostolos Pappas, Ph.D., is a professional member of the Institute of Food Technology. He started his professional career as a research biochemist in the Skin Research Center of Johnson & Johnson and later served as a group leader at Munich Biotech, where he worked on cancer research. Thereafter he returned to Johnson & Johnson, where he is currently a Research Manager and Fellow focusing on lipid metabolism research. He has authored numerous scientific publications, patent applications, and books.

Efforts to describe and model the molecular structure of biological membranes go back to the beginning of the last century. In 1917, Langmuir described membranes as a layer of lipids one molecule thick [1]. Eight years later, Gorter and Grendel concluded from their studies that "the phospholipid molecules that formed the cell membrane were arranged in two layers to form a lipid bilayer" [2]. Danielli and Robertson proposed, in 1935, a model in which the bilayer of lipids is sequestered between two monolayers of unfolded proteins [3], and the currently still accepted fuid mosaic model was proposed by Singer and Nicolson in 1972 [4]. Among those landmarks of biomembrane history, a serendipitous observation made by Alex Bangham during the early 1960s deserves undoubtedly a special place. His fnding that exposure of dry phospholipids to an excess of water gives rise to lamellar structures [5] has opened versatile experimental access to studying the biophysics and biochemistry of biological phospholipid membranes. Although during the following 4 decades biological membrane models have grown in complexity and functionality [6], liposomes are, besides supported bilayers, membrane nanodiscs, and hybrid membranes, still an indisputably important tool for membrane b- physicists and biochemists. In vol. II of this book, the reader will fnd detailed methods for the use of liposomes in studying a variety of biochemical and biophysical membrane phenomena concomitant with chapters describing a great palette of state-of-the-art analytical technologies.

Cell membranes are not, as once believed, inert structures designed to contain the cell contents, but are in fact dynamic structures that are as me- bolically active as the cytosol and other cellular compartments they surround. Thus membranes not only contain mixtures of lipid and phospholipids, but also many proteins both embedded deeply within the membrane structure itself and also more loosely attached on the membrane surfaces. Though many such proteins have long been known to act as transport proteins, ion channels, hormone receptors, G proteins, cytoskeletal anchorage points, and so on, the major advance of recent years is the increasing understanding that the lipids and phospholipids in the membrane bilayer itself are also metabolized to b- logically active products that can diffuse either in the cytosol or in the m- brane bilayer to control the function of other proteins. Thus the concept of lipid-derived second messengers is now firmly established.

Since their discovery over 60 years ago, eicosanoids have come to represent a diverse family of bioactive lipid modulators, including prostaglandins, thromboxanes, leukotrienes, lipoxins, isoprostanes, hepoxilins, hydroxy acids, epoxy and hydroxy fatty acids. This book contains conference presentations regarding the regulation of eicosanoid enzymes and, in particular, cyclooxygenases, lipoxygenases, and phospholipases. In addition, the latest evidence over the last seven years has led to the identification of a number of receptors for these bioactive lipids. The new field of isoprostanes is also represented. It has become increasingly evident that eicosanoids play a critical role in signal transduction, both in normal cells and in pathological processes. These aspects are discussed in relation to cellular events, such as apoptosis, angiogenesis, and cancer prevention and treatment.

Lipobiology is an interdisciplinary field which incorporates critical aspects of lipid and lipoprotein chemistry into the disciplines of cell biology and physiology. During the last decade, advances in our understanding of the structure and function of lipids, biological membranes and lipid-derived second messengers have underscored the importance of lipids in the regulation of cellular function. This series focuses on salient aspects of the role of lipids in metabolic regulation and cellular activation, with emphasis on emerging concepts and technologies. One goal of this series is to formulate cohesive criteria upon which a foundation for the evaluation of recent work can be based and future directions of research identified.
