This book provides a comprehensive description of sterols and their novel biological roles in mammalian signaling, the book covers their biosynthesis and structure, describes sterol receptor -mediated actions, their tissue distribution and their role in disease. It offers insight into new research findings, focusing specifically on novel discoveries in bile acid and oxysterol signaling, including the lanosterol-to-cholesterol intermediates. Special attention is paid on the sex distribution of these sterols (male or female) and their sexually dimorphic roles in mammalian species, such as human, rat and mouse. Since sterols and drugs (xenobiotics) use many identical receptor-mediated signaling pathways, the book will be interesting for researchers working on the cross-road of endogenous and xenobiotic metabolism, it is intended for advanced students and scientists in molecular biology and biochemistry as well as for medical doctors in hepatology.
The Seventh International Symposium on the Structure and Function of Plant Lipids took place at the University of California, Davis, California July 27th to August 1st, 1986. This was the first time the Symposium was held in the United States. The list of previous host cities reads, Norwich, Karlsruhe, Goteborg, Paris, Groningen, Neuchatel. The addition of Davis to this distinguished list was made by the organizers with the doubts of people who give invitations to parties - will anybody come? In fact 155 participants registered and there were 21 spouses in attendance. The scientific program was composed of nine sessions: biochemistry of isoprenoids and sterols, function of isoprenoids and sterols, structure and function of lipids, biosynthesis of complex lipids, fatty acid oxygenases and desaturases, medium and long chain fatty acids, interaction of university, government and industrial research, algal lipids, and genetics and biotechnology. In addition to these sessions of plenary lectures, there were four poster sessions in which about 140 posters were presented. All of this was packed into four days, and there was some comment about the scarcity of time to ask questions of the speakers, discuss the posters and even to eat lunch. The compression of the program was a result of the continued desire of the organizing committees to avoid concurrent sessions. The congregation of participants into a single session increases interaction and generates a feeling of unity at these symposia.
Leading international scientists bring current and developing topics in sterol research together in Biochemistry and Function of Sterols. The authors are experts in each major area of sterol research-medicine, biochemistry, chemistry, and agriculture. Each chapter features the current state of research as well as new and developing research topics. Throughout the volume the focus is on the major and expanding areas of sterol biochemistry and function of sterols in all classes or organisms. The broad scope of this work embraces many disciplines and will be of interest to a variety of researchers, students, and lay people. Professors will find Biochemistry and Function of Sterols an excellent choice as a textbook for courses on steroid, lipid, or plant biochemistry.
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.
Living organisms are separated from the outside world by their membranes, which perform important roles for maintaining their lives. Sterols are indispensable com­ ponents in eukaryotic organisms for stabilizing membranes composed of phospho­ lipid bilayers. Most prokaryotic organisms, on the other hand, do not contain sterols in their membranes, although recent studies indicated that the bacterium Methylo­ coccus capsulatus produces sterols 1) and many strains of Mycoplasma, bacteria without cell walls, require sterols as an essential growth factor 2). Some bacterial species synthesize hopanoids which are hypothesized to function like st~rols in eu­ karyotic organisms 3). Significance of ergosterol in fungi has been recognized from the fact that the yeast Saccharomyces cerevisiae requires ergosterol for growth, when cultured in a strictly anaerobic condition "'. l:.lectron microscopic studies showed that membrane structures disappeared in the yeast grown anaerobically without a supplement of ergosterol 5.6), indicating the necessity of ergosterol for membrane biogenesis. Further confirmation of the significant role of ergosterol in the membranes was derived from the studies on polyene antibiotics. In the presence of polyenes such as nystatin, filipin and amphotericin B, fungal cells lose selective permeability of the membranes, since polyenes interact with ergosterol, such that the structure of the fungal membranes is disrupted 7).
This is the third edition of this advanced textbook, written with two major objectives in mind. One is to provide an advanced textbook covering the major areas in the fields of lipid, lipoprotein, and membrane biochemistry, and molecular biology. The second objective is to provide a clear summary of these research areas for scientists presently working in these fields. The volume provides the basis for an advanced course for students in the biochemistry of lipids, lipoproteins and membranes. The book will satisfy the need for a general reference and review book for scientists studying lipids, proteins and membranes. Excellent up-to-date reviews are available on the various topics covered. A current, readable, and critical summary of these areas of research, it will allow scientists to become familiar with recent developments related to their own research interests, and will help clinical researchers and medical students keep abreast of developments in basic science that are important for subsequent clinical advances.
