Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it Samuel Johnson, 18 April, 1775* Sterols are among the most studied groups of natural products with interest commencing in the 19th century and running to the present. Investigations have embraced the refinement of separation procedures, the development of new analytical techniques and instrumentation for structure elucidation, the unravelling of biosynthetic mechanisms, the determination of the physiological functions of sterols, and the role they play in health and disease. In the past 20-30 years interest in the medical implications of sterol biochemistry, studies on the sterols of plants, algae and fungi, and the identification of the many unusual sterols from marine organisms have proceeded in parallel and somewhat independently. Although the motiva tion and goals for the various lines of investigation have differed widely the researchers working in each of these areas have contributed a wealth of knowledge to the literature relating to the analysis of sterols and many diverse new sterols have been discovered. We conceived this book as a modest attempt to bring together some of this literature in the hope that it may be helpful to newcomers to sterol research. We had originally intended to produce a 'handbook' outlining in detail the protocols to be followed for sterol extraction, chromatography, NMR analysis, etc. in order to identify the components of a sterol mixture.

Part of the IFT Press series, this book reviews the myriad published information on bioactive components derived from marine foods, enabling researchers and product developers to select appropriate functional ingredients for new products. Chapters cover foods and food ingredients from both animal and plant marine sources, focusing on those which demonstrate biological properties and whose constituent compounds have been isolated and identified as potentially active. This book further addresses the biological activities of PUFAs (Polyunsaturated fatty acids), oils, phospholipids, proteins and peptides, fibres, carbohydrates, chitosans, vitamins and minerals, fucoxantin, polyphenols, phytosterols, taurine, amongst others. These components, found in a variety of marine-derived foods, have been demonstrated to have preventative properties with regard to hypertension, oxidative stress, inflammation, cardiovascular diseases, cancer and other human diseases. Extraction methods and analysis techniques are also addressed. Intended for food scientists, food technologists and food engineers in academia, industry and government, this book reviews the substantial quantity of current research in this fast-moving and commercially valuable sector of food and nutrition science.

The Biology of Cholesterol and Related Steroids focuses on the study of sterols in relation to living organisms. The publication first takes a look at the analysis of sterols and related steroids and the distribution of sterols and related steroids in nature, as well as the processes of extraction and separation and presence of sterols in plants, fungi, vertebrates, and invertebrates. The text then ponders on biosynthesis of sterols and metabolism of cholesterol. Topics include formation of fatty acid esters of cholesterol, steroid hormones, biosynthetic pathway to sterols, reaction mechanisms, and comparative aspects of sterol synthesis. The manuscript examines the developmental aspects of cholesterol metabolism and sterols in biological membranes. The book also reviews cholesterol synthesis in animal tissues, sterol metabolism in isolated cells, and epidemiology of the plasma cholesterol. Discussions focus on selection of statistical populations, genetic influences, regulation of sterol synthesis, general aspects of sterol metabolism, and removal of cell cholesterol in vivo. The publication is a dependable source of data for biochemists and readers interested in the biology of cholesterol and steroids.

Lipids have been in clinical use as components of intravenous nutrition for over 50 years. Over the last 15 years, new and improved lipids that include olive oil and/or fish oil have replaced the more traditional ones. These new lipids offer the opportunity to deliver high amounts of fatty acids and possess different functional properties: in particular, they can influence inflammatory processes, immune responses and hepatic metabolism. This book brings together articles written by leading international authorities in the area of intravenous lipids. Contributions discuss the latest findings in the field, ranging from pre-clinical research to the most recent clinical trials. Lipid functionality and utility in pediatric, adult surgical and critically ill patients are covered, as is the use of lipids in long-term home parenteral nutrition. Addressing a broad spectrum of topics, this publication provides a wealth of information for basic scientists, clinical researchers and clinical practitioners alike.

Neuroscience Perspectives provides multidisciplinary reviews of topics in one of the most diverse and rapidly advancing fields in the life sciences.Whether you are a new recruit to neuroscience, or an established expert, look to this series for 'one-stop' sources of the historical, physiological, pharmacological, biochemical, molecular biological and therapeutic aspects of chosen research areas.The last decade has seen tremendous advances in our understanding of the pathobiology of Alzheimer's disease. These will lead to the first generation of drugs aimed at prevention rather than cure. This book covers some of the most important and exciting of these advances, with chapters written by many of the leading researchers in the field.With genetic studies as a backbone to this volume many chapters are devoted to the function and regulation of amyloid b-protein precursor (APP) and apolipoprotein E (ApoE). Other chapters describe cell biological approaches helping to piece together the link between the genetic alterations and the phenotype we call Alzheimer's disease.Although APP and its proteolytic cleavage product, amyloid b-protein, do not answer all the questions, detailed research into this system has undoubtedly increased our knowledge of the pathobiology of AD and has lead to the identification of other risk factors. Understanding the role of ApoE in the pathology of Alzheimer's disease promises to open a whole new field in AD research.* * Reviews the current knowledge of the pathogenesis of Alzheimer's Disease from a clinical perspective to a genetic and cell biological perspective* A comprehensive description of the role of amyloid B-protein precursor in Alzheimer's disease.* Up-to-date research data* Clear illustrations complement the text

This book comprehensively reviews several aspects of cholesterol oxidation products: cholesterol oxidation mechanisms, analytical determination, origin and content of these compounds in foods and biological samples, and their biological effects, with an emphasis on recent advances in these fields. Information on different aspects of phytosterol oxidation is reviewed. Little research has been conducted on the analysis of mixed sterol oxidation products. Mixed diets containing both cholesterol and phytosterols can contain a complex array of oxidation products generated from these sterols. Research into the problem of analyzing these complex mixtures of compounds is highlighted.
