Download or read book Industrial Applications of Homogeneous Catalysis written by A. Mortreux and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catalysts are now widely used in both laboratory and industrial-scale chemistry. Indeed, it is hard to find any complex synthesis or industrial process that does not, at some stage, utilize a catalytic reaction. The development of homogeneous transition metal catalysts on the laboratory scale has demonstrated that these systems can be far superior to the equivalent heterogeneous systems, at least in terms of selectivity. is an increasing interest in this field of research from both an Thus, there academic and industrial point of view. In connection with the rapid developments in this area, four universities from the E.E.C (Aachen, FRG; Liege, Belgium; Milan, Italy; and Lille, France) have collaborated to organise a series of seminars for high-level students and researchers. These meetings have been sponsored by the Commission of the E.E.C and state organizations. The most recent of these meetings was held in Lille in September 1985 and this book contains updated and expanded presentations of most of the lectures given there. These lectures are concerned with the field of homogeneous transition metal catalysis and its application to the synthesis of organic intermediates and fine chemicals from an academic and industrial viewpoint. The continuing petroleum crisis which began in the early 1970s has given rise to the need to develop new feedstocks for the chemical industry.

Available in PDF, EPUB and Kindle. Book excerpt: Bridges the gap between the chemistry of small molecule neuromodulators and the complex pattern of neurodegenerative disorders Written by an experienced neurochemist, this book focuses on the main actors involved in neurodegenerative disorders at a molecular level, and places special emphasis on structural aspects and modes of action. Drawing on recent data on enzyme structure, mode of action, and inhibitor design, it describes?from a biochemical point of view?the six most important neurotransmitter systems and their constituent enzymes and receptors. Misfolding and aggregation of proteins within the brain is also covered. In addition, the book surveys a wide range of proven and prospective therapeutic agents that modulate key processes in the brain, from their chemical synthesis to their mode of action in model systems as well as in the patient. Chemical Biology of Neurodegeneration: A Molecular Approach is presented in two parts. The first introduces the neurotransmitter systems and provides a general explanation of the synapse and a description of the main structures involved in neurotransmission that can be considered therapeutic targets for disorders of the central nervous system. The second part presents molecular and chemical aspects directly involved or affected in neurodegeneration, including the metabolism of neurotransmitters, enzymes processing neurotransmitters, protein misfolding, and therapeutic agents. -Uses an interdisciplinary approach to bridge the gap between the basic biochemical events in a nerve cell and their neurological effects on the brain -Places emphasis on the chemistry of small molecule modulators that are potential lead molecules for new drugs -Covers six key neurotransmitter systems and their enzymes and receptors?dopaminergic, noradrenergic, serotonergic, cholinergic, GABAergic, and glutamatergic Chemical Biology of Neurodegeneration: A Molecular Approach is a key resource for medicinal chemists, neurobiologists, neurochemists, biochemists, molecular biologists, and neurophysiologists.

Download or read book Fragrance Chemistry written by Ernst T. Theimer and published by Elsevier. This book was released on 2012-12-02 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been prepared as an introduction to the chemistry of odorous molecules. While there exist a number of works of an encyclopedic nature which cover this field, there is none which treats the subjectin an instructional fashion. To fill this gap, a group of scientists, types from the chemical point of view, to present to the reader the panorama of those molecules that stimulate the sense of smell. To make the picture complete, the chapters that are strictly chemical in content are preceded by several that introduce the topics of the physiology of the olfactory system, the current hypotheses on the mechanism of the sense of smell, and the structure-odor relationships in odorous molecules. There is also a treatment of analytical techniques which have become important to fragrance chemical research and testing.
