Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the methodology used to determine sterol content in coral reef food webs, and how sterol data is used in trophic ecology studies. The authors briefly explain the basics of gas chromatography and mass spectrometry as necessary tools to confidently separate, identify, and quantify sterols. Sterols from different sponge families have been described, however, few studies have been conducted involving the sterols of the freshwater sponge compared to those of the marine environment. The number of sterols present varies with the species, and this characteristic make it possible to use this data as a chemosystematic marker. In olive oil, sterols constitute the majority of the unsaponifiable fraction. In recent years, there has been increased interest in the sterols of olive oil due to their health benefits and their importance to virgin olive oil quality. Thus, the authors discuss recent findings concerning the effect of cultivars on the sterolic profile of extra virgin olive oil. The subsequent study aims to contribute to the optimisation and valorisation of virgin olive oil quality in the world olive-producing areas. This work was carried out on the study of virgin olive oil from two new olive varieties obtained through uncontrolled crossings. The sterolic fraction of argan oil is also compared to that of olive oil. The total phytosterol content ranged from 1700.80 mg/kg in chemlali oil to 150.40mg/kg in argan oil. In contrast to chemlali oil in which Î2-sitosterol is predominant, the major sterols detected in argan oil is schottenol and spinasterol. Additionally, the standards of the European Union legislation for fats and oils can help to verify olive oil authenticity using the sterolic profile. As such, this collection critiques the existing regulatory methods and standards, highlights weaknesses and proposes possible solutions to safeguard the consumer and protect the olive oil market. In closing, the authors examine the analysis of phytosterols, a multistage procedure that includes extraction, isolation/purification as a group of related compounds and a chromatographic technique for separation, identification, and quantification.

Book excerpt: 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.

Book excerpt: 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

Book excerpt: The consumption of phytosterols (plant sterols and/or stanols) can reduce cardiovascular risk by reducing hypercholesterolemia. In addition to reducing intestinal cholesterol absorption, phytoserols (PS), which are structurally similar to cholesterol, have other potential beneficial effects in humans. There are a wide range of plants that have phytosterols in their composition. In this book, the food sources of phytosterols are explored. The authors evaluate whether a decrease in carotenoids associated with the consumption of a therapeutic dose of PS alters oxidative stress parameters. Furthermore, the characterisation of oils by phytosterols analysis was studied and is examined in this book. An overview of phytosterols in olive oil is given as well, particularly, the use of HPLC and GC coupled to various detection systems to isolate sterols from olive oil in order to focus on the occurrence of phytosterols and their role in human health.
