Download or read book Analysis of Sterols written by J. Goad and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 453 pages. 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.

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

Download or read book The Metabolism Structure and Function of Plant Lipids written by Paul K. Stumpf and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 653 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Proprotein Convertases written by Abdel-Majid Khatib and published by Morgan & Claypool Publishers. This book was released on 2013-02 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proprotein convertases (PCs) are a family of proteases including PC1, PC2, Furin, PC4, PACE4, PC5, and PC7. These enzymes are involved in the maturation of many precursor proteins involved in the process of tumorigenesis and metastasis. Since their discovery, PCs were suggested as potential targets for anti-cancer therapy, and their activity was found to directly affect tumor cell proliferation, migration invasion, and the malignant phenotypes of tumor cells. Here, we discuss a number of previous and recent findings on the PCs features, their implication in the regulation of multiple cellular functions that impact on the invasive/metastatic potential of cancer cells, and their clinical relevance in cancer patients. Among the substrates of the proprotein convertases, various growth factors, their receptors, adhesion molecules, and proteases were identified. The PCs are inhibited by endogenous and exogenous inhibitors. To date, only pro7B2, a specific chaperone of PC2, and the granine-like precursor of neuroendocrine protein proSAAS, a selective ligand of PC1, have been identified as endogenous inhibitors of the PCs found in the regulated pathway. However, only PCs prosegments, several bioengineered inhibitors, peptides, and non-peptide compounds were found to inhibit the activity of the PCs found in the secretory pathway.

Download or read book The Plant Plasma Membrane written by Angus S. Murphy and published by Springer Science & Business Media. This book was released on 2010-11-11 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: In plant cells, the plasma membrane is a highly elaborated structure that functions as the point of exchange with adjoining cells, cell walls and the external environment. Transactions at the plasma membrane include uptake of water and essential mineral nutrients, gas exchange, movement of metabolites, transport and perception of signaling molecules, and initial responses to external biota. Selective transporters control the rates and direction of small molecule movement across the membrane barrier and manipulate the turgor that maintains plant form and drives plant cell expansion. The plasma membrane provides an environment in which molecular and macromolecular interactions are enhanced by the clustering of proteins in oligimeric complexes for more efficient retention of biosynthetic intermediates, and by the anchoring of protein complexes to promote regulatory interactions. The coupling of signal perception at the membrane surface with intracellular second messengers also involves transduction across the plasma membrane. Finally, the generation and ordering of the external cell walls involves processes mediated at the plant cell surface by the plasma membrane. This volume is divided into three sections. The first section describes the basic mechanisms that regulate all plasma membrane functions. The second describes plasma membrane transport activity. The final section of the book describes signaling interactions at the plasma membrane. These topics are given a unique treatment in this volume, as the discussions are restricted to the plasma membrane itself as much as possible. A more complete knowledge of the plasma membrane’s structure and function is essential to current efforts to increase the sustainability of agricultural production of food, fiber, and fuel crops.
