Chirality is a fundamental, persistent, but often overlooked feature of all living organisms on the molecular level as well as on the macroscopic scale. The high degree of preference for only one of two possible mirror image forms in Nature, often called biological homochirality is a puzzling, and not yet fully understood, phenomenon. This book covers biological homochirality from an interdisciplinary approach - contributions range from synthetic chemists, theoretical topologists and physicists, from palaeontologists and biologists to space scientists and representatives of the pharmaceutical and materials industries. Topics covered include - theory of biochirality, origins of biochirality, autocatalysis with amplification of chirality, macroscopic (present) biochirality, fossil records of chiral organisms - paleochirality, extraterrestrial origin of chirality, exceptions to the rule of biological homochirality, D-amino acids, chemical transfer of chirality, PV effects, and polarised radiation chemistry.

Following on from Advances in BioChirality, Progress in Biological Chirality provides a unique summary and review of the most recent developments in the field of biochirality. Living organisms use only one enantiomer of chiral molecules in the majority of biologically important processes. The exact origin and mechanisms for this surprising selectivity are not yet known. This book discusses current research aimed at identifying the scientific reasons that may contribute to this phenomenon. Progress in Biological Chirality takes an interdisciplinary approach to this exciting field, covering a wide range of topics, such as, theory, palaeontology and food technology, to name but a few. This book presents findings via a broad spectrum of scientific approaches making it an excellent overview of Biological Chirality, suitable for postgraduate students, practitioners and researchers in the field of chemistry, biochemistry, biology, palaeontology, and food science with an interest in Chirality. This book contains 32 chapters written by Authors, who are leading authorities in the field Presents the most recent research taking place in this highly challenging field Contains both reference material for the specialist and provides an overview for those who are interested in the fundamental problems of biology and chemistry

Organometallic chemistry is based on the reactions and use of a class of compounds (R-M) that contain a covalent bond between carbon and metal. They are prepared either by direct reaction of the metal with an organic compound or by replacement of a metal from another organometallic substance. Research in organometallic chemistry is also conducted in the areas of cluster synthesis, main-group derivatives in unusual oxidation states, organometallic polymers, unstable organometallic compounds and intermediates in matrices, structure determination of organometallic compounds in the solid state [X-ray diffraction] and gaseous states [electron diffraction], and mechanisms of reactions of transient silylenes and related species. In addition to the traditional metals and semimetals, elements such as selenium, lithium and magnesium are considered to form organometallic compounds, e.g. organomagnesium compounds MeMgI, iodo(methyl)magnesium and diethylmagnesium, which are Grignard reagents an organo-lithium compound BuLi butyllithium; Organometallic compounds often find practical use as catalysts, the processing of petroleum products and the production of organic polymers.

Advances in Asymmetric Autocatalysis and Related Topics provides various viewpoints on the important developments in asymmetric autocatalysis that have occurred in the past few years, also including brand new information in the field. Asymmetric autocatalysis is a chemical reaction which leads from achiral starting materials to chiral products, and in which the product accelerates its own formation reaction (conventional catalysis) and promotes the prevalence of its own chiral configuration (asymmetric induction). The combination of these two effects in the same reaction was unprecedented before 1995 when it was first described by Kenso SOAI at the Tokyo University of Science. Since then, several new combinations of this effect have been found, most intriguingly the possibility of absolute asymmetric synthesis, which is the spontaneous formation of the excess of one of the enantiomers of the product, a dream of organic chemists for more than a century. The book contains expert-contributed chapters that describe the most exciting recent developments in the field of the Soai reaction and in related topics, ranging from mechanistic studies and theoretical research, to very practical problems in chiral syntheses and products. Features contributions from global experts, including several chapters from Kenso Soai and expert colleagues Focuses on recent developments in the field of asymmetric autocatalysis and newly reported findings Explores the Soai reaction, new developments, and the light it sheds on homochirality in certain biomolecules

Provides the background, tools, and models required to understand organic synthesis and plan chemical reactions more efficiently Knowledge of physical chemistry is essential for achieving successful chemical reactions in organic chemistry. Chemists must be competent in a range of areas to understand organic synthesis. Organic Chemistry provides the methods, models, and tools necessary to fully comprehend organic reactions. Written by two internationally recognized experts in the field, this much-needed textbook fills a gap in current literature on physical organic chemistry. Rigorous yet straightforward chapters first examine chemical equilibria, thermodynamics, reaction rates and mechanisms, and molecular orbital theory, providing readers with a strong foundation in physical organic chemistry. Subsequent chapters demonstrate various reactions involving organic, organometallic, and biochemical reactants and catalysts. Throughout the text, numerous questions and exercises, over 800 in total, help readers strengthen their comprehension of the subject and highlight key points of learning. The companion Organic Chemistry Workbook contains complete references and answers to every question in this text. A much-needed resource for students and working chemists alike, this text: -Presents models that establish if a reaction is possible, estimate how long it will take, and determine its properties -Describes reactions with broad practical value in synthesis and biology, such as C-C-coupling reactions, pericyclic reactions, and catalytic reactions -Enables readers to plan chemical reactions more efficiently -Features clear illustrations, figures, and tables -With a Foreword by Nobel Prize Laureate Robert H.

The subject of aluminium and Alzheimer's disease has been plagued with controversy. This controversy has served to obscure much of the scientific research in this field, and subsequently has obscured the possibility that aluminium is a contributory factor in the aetiology of Alzheimer's disease. This book brings together many of the world's leading scientists researching aluminium and life and contains their critical summaries on the known facts about aluminium toxicity in man and to offer an opinion on the implications of this knowledge on a link between aluminium and Alzheimer's disease. The subject areas of the chapters were chosen to reflect the myriad of ways that aluminium is known to impact upon mammalian physiology and function and range from clinical studies, through animal models of disease to the detailed biochemistry of aluminium toxicity. Chapters are also included on epidemiology and other factors involved in the aetiology of Alzheimer's.This is the first time that this subject has been treated in such a comprehensive manner. The research detailed in each chapter, includes the latest research in the field, it has been critically appraised and this appraisal has been used by each author to present an informed opinion of its relevance to aluminium and Alzheimer's disease. The chapters are much more than reviews; they are a statement of the state of the art and of what the future may hold for research in this field. As a whole they show the high quality of research that has been carried out in our efforts to understand the toxicity of aluminium in man and that we are far away from discounting the possibility that aluminium is a contributory factor in the aetiology of Alzheimer's disease.
