Download or read book Combinatorics of Genome Rearrangements written by Guillaume Fertin and published by MIT Press. This book was released on 2009 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive survey of a rapidly expanding field of combinatorial optimization, mathematically oriented but offering biological explanations when required. From one cell to another, from one individual to another, and from one species to another, the content of DNA molecules is often similar. The organization of these molecules, however, differs dramatically, and the mutations that affect this organization are known as genome rearrangements. Combinatorial methods are used to reconstruct putative rearrangement scenarios in order to explain the evolutionary history of a set of species, often formalizing the evolutionary events that can explain the multiple combinations of observed genomes as combinatorial optimization problems. This book offers the first comprehensive survey of this rapidly expanding application of combinatorial optimization. It can be used as a reference for experienced researchers or as an introductory text for a broader audience. Genome rearrangement problems have proved so interesting from a combinatorial point of view that the field now belongs as much to mathematics as to biology. This book takes a mathematically oriented approach, but provides biological background when necessary. It presents a series of models, beginning with the simplest (which is progressively extended by dropping restrictions), each constructing a genome rearrangement problem. The book also discusses an important generalization of the basic problem known as the median problem, surveys attempts to reconstruct the relationships between genomes with phylogenetic trees, and offers a collection of summaries and appendixes with useful additional information.

Download or read book Making And Breaking Symmetry In Chemistry Syntheses Mechanisms And Molecular Rearrangements written by Michael James Mcglinchey and published by World Scientific. This book was released on 2022-03-09 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The elucidation of reaction mechanisms generally requires the carefully designed control of molecular symmetry to distinguish between the many possible reaction pathways. Making and Breaking Symmetry in Chemistry emphasises the crucial role played by symmetry in modern synthetic chemistry. After discussion of a number of famous classical experiments, the advances brought about by the introduction of new techniques, in particular NMR spectroscopy, are exemplified in numerous cases taken from the recent literature. Experimental verification of many of the predictions made in Woodward and Hoffmann's explication of the Conservation of Orbital Symmetry are described. Applications that involve the breaking of molecular symmetry to resolve these and other mechanistic problems in organic, inorganic and organometallic chemistry are presented in the first sections of the book, together with many examples of the detection of hitherto hidden rearrangement processes.Subsequently, under the aegis of making molecular symmetry, examples of the preparation of highly symmetrical molecules found in the organic, organometallic or inorganic domains are discussed. These include Platonic hydrocarbons or boranes, tetrahedranes, cubanes, prismanes, dodecahedrane, fullerene fragments such as corannulene, sumanene or semibuckminsterfullerene, and other systems of unusual geometries or bonding characteristics (Möbius strips, molecular brakes and gears, Chauvin's carbomers, Fitjer's rotanes, persubstituted rings, metal-metal multiple bonds, etc.). The text also contains vignettes of many of the scientists who made these major advances, as well as short sections that briefly summarise key features of important topics that underpin the more descriptive material. These include some aspects of chirality, NMR spectroscopy, and the use of isotopic substitution to break molecular symmetry. A brief appendix on point group symmetry and nomenclature is also helpfully provided.

Download or read book Synthetic Coordination Chemistry written by Julian A. Davies and published by World Scientific. This book was released on 1996 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although coordination chemistry naturally centers on the synthesis of coordination compounds, the synthesis of these materials is typically not an end in itself. Coordination compounds are utilized in all branches of chemistry; from theoretical modeling to industrial and consumer products. While a large amount of information is available on coordination chemistry in general and synthetic methods in particular, no comprehensive work has been presented on the preparation of coordination compounds with an emphasis on synthetic strategies rather than on detailed descriptions of specific syntheses. The goal of this book is to provide an approach to coordination chemistry that is based upon preparative strategies.The main aim of the authors is to present a systematic classification of synthetic reactions rather than an encyclopedic listing of experimental results. Hence, the coverage is more selective than exhaustive. Despite this, the book provides access to the original literature with ca. 2000 references. The edition is well-illustrated and contains almost 250 schemes, figures and illustrations of crystal structures of selected complexes.

Download or read book Domino and Intramolecular Rearrangement Reactions as Advanced Synthetic Methods in Glycoscience written by Zbigniew J. Witczak and published by John Wiley & Sons. This book was released on 2016-01-14 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book consists of a brief introduction, a foreward provided by professor Danishefsky of Columbia University, and about 14 - 16 chapters, each written by one or two eminent scholars/authors describing their recent research in the area of either domino reactions or intramolecular rearrangements in carbohydrate chemistry. Three or four chapters will be reviews. The domino (cascade, tandem) reactions are always intramolecular. They are usually very fast, clean and offer highly complex structures in a one pot process. Intramolecular rearrangements offer very similar advantages and often lead to highly complex products as well. Although many recently isolated carbohydrates fulfill various sophisticated functions, their structures are often very complex. The editors cover the broadest scope of novel methodologies possible. All the synthetic and application aspects of domino/cascade reactions are explored in this book. A second theme that will be covered is intramolecular rearrangement, which is also fast, stereoselective, and often constitutes one or more steps of domino / cascade process. Selected examples of intramolecular rearrangements are presented. Together, both processes offer an elegant and convenient approach to the synthesis of many complex molecules, which are normally difficult to synthesize via alternative routes. It appears that domino and intramolecular rearrangements are ideally suited to synthesize certain specific modified monosaccharides. What is particularly important is that both processes are intermolecular and almost always yield products with very well-defined stereochemistry. This high definition is absolutely crucial when synthesizing advanced, modified mono and oligosaccharides. The choice of contributors reflects an emphasis on both therapeutic and pharmacological aspects of carbohydrate chemistry.

Download or read book Worked Solutions in Organic Chemistry written by James M. Coxon and published by CRC Press. This book was released on 1997-12-18 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book illustrates and teaches the finer details of the tactics and strategies employed in the synthesis of organic molecules. As well as providing model answers to the problems, the book discusses, in detail, the reasons why particular strategies are chosen, and why, in given circumstances, alternative methods or routes may or may not be appropriate. As such it could be used as a stand alone volume for the teaching of organic chemistry with a modern and appropriate emphasis on synthesis. Extensive cross referencing to Principles of Organic Synthesis allows the two books to be used as companion volumes.
