Disorders Of Lipid Metabolism

For the past 30 years I have been teaching lipid biochemistry to'inedical students, graduate students, and undergraduate students. The major topics covered in my courses were fatty acids, prostaglandins, leukotrienes, phospholipids, glyco lipids, triacylglycerols, cholesterol, bile acids, and plasma lipoproteins. Empha sis was placed on the regulation and disorders of lipid metabolism. The latter included hyperlipidemias, atherosclerosis, and alcohol-induced liver damage. In this volume, I have chosen to focus on the disorders of lipid metabolism at a level appropriate both for medical students and for graduate and undergradu ate students majoring in the biological sciences. The biochemistry, nutrition, genetics, and cell biology aspects of lipids and lipid metabolism will be covered as they relate to lipid disorders. I am not aware of any textbook that integrates the disorders of lipid metabolism in this manner. Chapter 1 includes a brief discussion of the basic structures, properties, and metabolism of lipids. This chapter is not very detailed, since the material covered is available in basic textbooks on biochemistry. The major fpcus of this volume is the various lipid disorders, with emphasis on polyunsaturated fatty acids, the molecular biology and pathogenesis of the hyperlipidemias, dietary and drug therapy for the hyperlipidemias, and alcohol-induced liver damage. The material presented has been obtained from several textbooks on biochemistry and from a variety of recent articles in the scientific literature.

Cellular and Molecular Pathology of the Liver is extensive, complex and ranges from the understanding the basic molecular mechanisms that dictate everything from liver homeostasis to liver disease. Molecular Pathology of the liver is complicated due to some of the important functions inherent and unique to the Liver, including its innate ability to regenerate and the multitude of functions it plays for the wellbeing of an organism. With all this in mind, Molecular Pathology of Liver Diseases is organized in different sections, which will coherently and cohesively present the molecular basis of hepatic physiology and pathology. The first two sections are key to understanding the liver anatomy and physiology at a cellular level and go on to define the molecular mechanics in various liver cell types. These sections also cover the existing paradigms in liver development, regeneration and growth. The next section is key to understanding the Molecular Pathology unique to liver diseases and associated phenotypes. The final sections are geared towards the existing knowledge of the molecular basis of many common and uncommon liver diseases in both neoplastic and non-neoplastic areas including pathologies associated with intra-hepatic and extra-hepatic biliary tree. Thus, this textbook is a one-stop reference for comprehending the molecular mechanisms of hepatic pathobiology. It is clearly unique in its format, readability and information and thus will be an asset to many in the field of Pathology and other disciplines.

Lipid Signaling and Metabolism provides foundational knowledge and methods to examine lipid metabolism and bioactive lipid signaling mediators that regulate a broad spectrum of biological processes and disease states.

Throughout, authors demonstrate how expanding our understanding of lipid mediators in metabolism and signaling enables opportunities for novel therapeutics. Emphasis is placed on bioactive lipid metabolism and research that has been impacted by new technologies and their new potential to transform precision medicine. Provides a clear, up-to-date understanding of lipid signaling and metabolism and the impact of recent technologies critical to advancing new studies Empowers researchers to examine bioactive lipid signaling and metabolism, supporting translation to clinical care and precision medicine Discusses the role of lipid signaling and metabolism in obesity, diabetes, fatty liver disease, inflammation, cancer, cardiovascular disease and mood-related disorders, among others

Presents the State-of-the-Art in Fat Taste Transduction A bite of cheese, a few potato chips, a delectable piece of bacon – a small taste of high-fat foods often draws you back for more. But why are fatty foods so appealing? Why do we crave them? Fat Detection: Taste, Texture, and Post Ingestive Effects covers the many factors responsible for the sensory appeal of foods rich in fat. This well-researched text uses a multidisciplinary approach to shed new light on critical concerns related to dietary fat and obesity. Outlines Compelling Evidence for an Oral Fat Detection System Reflecting 15 years of psychophysical, behavioral, electrophysiological, and molecular studies, this book makes a well-supported case for an oral fat detection system. It explains how gustatory, textural, and olfactory information contribute to fat detection using carefully designed behavioral paradigms. The book also provides a detailed account of the brain regions that process the signals elicited by a fat stimulus, including flavor, aroma, and texture. This readily accessible work also discusses: The importance of dietary fats for living organisms Factors contributing to fat preference, including palatability Brain mechanisms associated with appetitive and hedonic experiences connected with food consumption Potential therapeutic targets for fat intake control Genetic components of human fat preference Neurological disorders and essential fatty acids Providing a comprehensive review of the literature from the leading scientists in the field, this volume delivers a holistic view of how the palatability and orosensory properties of dietary fat impact food intake and ultimately health. Fat Detection represents a new frontier in the study of food perception, food intake, and related health consequences.

This book provides an authoritative and comprehensive source of information on the biochemical an metabolic aspects of digestion and absorption of different dietary fats and other lipids, with minimal discussion of the physical chemistry of the process, which has been covered in great detail in previous reviews. It is intended for both researchers and practitioners in the biomedical field who require detailed knowledge of the biomedical and metabolic transformations involed in the intestinal digestion and resynthesis of dietary fats and other lipids.

Lipids are functionally versatile molecules. They have evolved from relatively simple hydrocarbons that serve as depot storages of metabolites and barriers to the permeation of solutes into complex compounds that perform a variety of signalling functions in higher organisms. This volume is devoted to the polar lipids and their constituents. We have omitted the neutral lipids like fats and oils because their function is generally to act as deposits of metabolizable substrates. The sterols are also outside the scope of the present volume and the reader is referred to volume 28 of this series which is the subject of cholesterol. The polar lipids are comprised of fatty acids attached to either glycerol or sphingosine. The fatty acids themselves constitute an important reservoir of substrates for conversion into families of signalling and modulating molecules including the eicosanoids amongst which are the prostaglandins, thromboxanes and leucotrienes. The way fatty acid metabolism is regulated in the liver and how fatty acids are desaturated are subjects considered in the first part of this volume. This section also deals with the modulation of protein function and inflammation by unsaturated fatty acids and their derivatives. New insights into the role of fatty acid synthesis and eicosenoid function in tumour progression and metastasis are presented.

Even though initially considered as a passive means for storing energy, lipids are now regarded as multifaceted molecules with crucial structural and functional activities. For instance, some of them play essential roles as key components of cell membranes whereas others act as signaling molecules in the regulation of cell homeostasis. In recent years, lipid research has attracted increasing interest because of the involvement of this class of compounds in human health. Indeed, a plethora of pathological conditions are characterized by alterations in lipid metabolism, such as cardiovascular diseases and brain disorders. This Special Issue is a collection of papers from different experts in lipid research, with the aim of providing new insights into the physiopathological involvement of lipids and their impact on human health. This collection also demonstrates the usefulness of interdisciplinary approaches in the development of novel methods to study and manipulate lipid metabolism, which may represent an attractive target for designing effective therapeutic strategies to counteract numerous pathologies.

This volume offers a detailed and comprehensive analysis of Endocrine Disrupting Chemicals (EDCs), covering their occurrence, exposure to humans and the mechanisms that lead to the parthogenesis of EDCs-induced metabolic disorders. The book is divided into three parts. Part I describes the physiology of the human endocrine system, with special emphasis on various types of metabolic disorders along with risk factors that are responsible for the development of these disorders. Part II addresses all aspects of EDCs, including their role in the induction of various risk factors that are responsible for the development of metabolic disorders. Part III covers up-to-date environmental regulatory considerations and treatment strategies that have been adopted to cure and prevent EDCs-induced metabolic disorders. This section will primarily appeal to clinicians investigating the causes and treatment of metabolic disorders. The text will also be of interest to students and researchers in the fields of Environmental Pharmacology and Toxicology, Environmental Pollution, Pharmaceutical Biochemistry, Biotechnology, and Drug Metabolism/Pharmacokinetics.
