Book Description
Volume 3 of the Carotenoids series moves into the area of biochemistry & biology, concentrating on how the carotenoid molecules are formed in nature & utilized or modified by living organisms. Animals cannot biosynthesize carotenoids de novo. Dietary carotenoids provide most of the vitamin A that is vital for health & development in humans & other mammals. The formation of vitamin A & the absorption, transport & deposition of carotenoids in tissues in mammals are described, followed by a detailed account of the diverse metabolic reactions by which dietary carotenoids undergo structural & stereochemical changes in birds, fish & invertebrate animals. The relevance of carotenoids for use as markers to trace food chains is also discussed. In keeping with the philosophy of the carotenoid series guidance on the application of some of the most important experimental procedures for studies of biosynthesis & metabolism are given in the final chapter. The information presented & analyzed by expert authors in this volume will serve as a useful reference source, & give valuable guidance on practical strategies & procedures, as a foundation for the exciting advances that can be expected in carotenoid biosynthesis & metabolism in the next few years.

Book Description
The impact of the retinoids in clinical practice has primarily been in dermatology. When Dr Werner Bollag began his basic research and screening programme in the early 1960's, the expectation was that the retinoids would have a major impact on oncology. However, the laboratory and clinical experiences of Bollag and his colleagues in Switzerland, Stuttgen and Orfanos in Germany, led to publications on both etretinates (Tigason) and isotretinoin (Roaccutane) in the years between 1972 and 1976 in the field of dermatology. In fact the first symposium on retinoid research held in Berlin in 1981 was almost entirely dermatological. A year later a retinoid workshop in Iowa was designed to provide a forum for dermatolog ists from the USA involved in specific protocols investigating oral retinoids. In the UK, research into the retinoids began rather later than in Continental Europe or in the USA, although Tigason was first marketed here. It was felt in late 1982 that as many dermatologists had relatively little experience with these compounds it would be appropriate to hold an International Symposium on retinoid therapy in the UK. Thus on 16-18 May 1983 in London, 37 speakers from 11 countries addressed an audience of 300, aminly UK, dermatologists. The scientific organizing committee consisted of but two persons Dr William Cunliffe of Leeds General Infirmary, representing the European Society of Dermatolo gical Research, and myself from Roche Clinical Research. The Symposium was held under the auspices of the ESDR and of Roche Products Limited.

Book Description
Selectivity is an increasingly important part of organic synthesis. The whole basis of organic chemistry, and especially organic synthesis, depends upon the selectivity which can be achieved in organic reactions. This concise textbook describes the strategies which can be adopted to improve selectivity, and the reactions which have been specially designed to afford high selectivity. The aim is to illustrate the range of processes to which these principles can be applied and the high degree of selectivity which can be achieved. Selectivity in Organic Synthesis aims to provide a solid introduction to this subject, focusing on the key areas and applications.

Book Description
Applications of MO Theory in Organic Chemistry is a documentation of the proceedings of the First Theoretical Organic Chemistry meeting. This text is divided into five sections. Section A contains contributions ranging from the stereochemistry of stable molecules, radicals, and molecular ions, through hydrogen bonding and ion solvation to mathematical analyses of energy hypersurfaces. Section B deals with theoretical studies of organic reactions, including basecatalyzed hydrolysis, protonation, epoxidation, and electrophilic addition to double and triple bonds. Section C consists of topics starting with a qualitative configuration interaction treatment of thermal and photochemical organic reactions, followed by ab initio treatments of photochemical intermediates and a consideration of the role of Rydberg and valence-shell states in photochemistry. Section D provides analyses of methods for the determination and characterization of localized MO and discussions of correlated electron pair functions. Section E covers a very wide range from the application of statistical physics to the treatment of molecular interactions with their environments to a challenge to theoretical organic chemists in the field of natural products, and an introduction to information theory in organic chemistry. This book is a good source of information for students and researchers conducting study on the many areas in theoretical organic chemistry.
