Knowledge of thc chemical behavior of trace compounds in the atmosphere has grown steadily, and sometimes even spectacularly, in recent decades. These developments have led to the emergence of atmospheric chemistry as a new branch of science. This book covers all aspects of atmospheric chemistry on a global scale, integrating information from chemistry and geochemistry, physics, and biology to provide a unified account. For each atmospheric constituent of interest, the text summarizes the principal observations on global distribution, chemical reactions, natural and anthropogenic sources, and physical removal processes. Coverage includes processes in the gas phase, in aerosols and c1ouds, and in precipitation, as well as biogeochemical cycles and the evolution of the atmosphere. Chemistry of the Natural Atmosphere, Second Edition, will serve as a textbook for senior undergraduate and graduate courses, and as an essential reference for atmospheric chemists, meteorologists, and anyone studying the biogeochemical cycles of trace gases. * Updated extensively from the highly respected first edition * Treats the global-scale chemistry and distribution of atmospheric trace constituents * Emphasizes observations and their interpretation * Provides background on transport and reaction kinetics for interpretation of observational data * Includes chemistry in the gas phase and in aerosols and clouds * Details chemical reaction pathways for the most important trace constituents * Describes pertinent biogeochemical cycles * Written by an author with more than 40 years of research experience in atmospheric chemistry
This book explores chemical bonds, their intrinsic energies, and the corresponding dissociation energies which are relevant in reactivity problems. It offers the first book on conceptual quantum chemistry, a key area for understanding chemical principles and predicting chemical properties. It presents NBO mathematical algorithms embedded in a well-tested and widely used computer program (currently, NBO 5.9). While encouraging a "look under the hood" (Appendix A), this book mainly enables students to gain proficiency in using the NBO program to re-express complex wavefunctions in terms of intuitive chemical concepts and orbital imagery.
Chemistry of Marine Natural Products explores the marine environment and its chemical composition. This book discusses the factors that contribute to the increasing interest in the study of marine environment. Organized into five chapters, this text starts with a discussion on the organic compound isoprenoids. This book then examines the sterol composition in several species, including crustaceans, echinoderms, mollusks, and invertebrates. This text also discusses phenols and its derivatives, including bromophenols and dibrophenol. Amino acids, carbohydrates, and polymers are also presented in this book. Other chapters explain the secondary metabolites, particularly amino acids and simple amines. This book further discusses the chemistry of fatty acids and determines whether marine animals and plants elaborate any distinct fatty acids. The final chapter explores the biogenetic relationship of hydrocarbons to fatty acids. This book is intended for chemists with an interest in the marine environment. Oceanographers, marine biologists, marine scientists, pharmacologists, researchers, teachers, and students will find this book extremely useful.
Natural products play an integral and ongoing role in promoting numerous aspects of scientific advancement, and many aspects of basic research programs are intimately related to natural products. The significance, therefore, of the 28th volume in the Studies in Natural Product Chemistry series, edited by Professor Atta-ur-Rahman, cannot be overestimated. This volume, in accordance with previous volumes, presents us with cutting-edge contributions of great importance. The first paper presents over 100 compounds obtained from Broussonetia spp., and discusses biological activities. This is followed by similar contributions dealing with the genus Licania and Ginkgo biloba. Additional papers describe in detail a number of interesting and important natural compounds or structural classes: retinoids, tetramic acid metabolites, isoprenylated flavonoids, plant polyphenols, crocin, marcfortine and paraherquamide, acaricides, podolactones, triterpene glycosides and sulfur-containing marine compounds. An additional paper focuses on the antitumor activities of lipids, and a final contribution deals with natural product amelioration of cancer chemotherapy-induced adverse reactions.

Lignans, by convention, are a group of natural products that are formed by linking two phenylpropanoid units (C C units) by oxidative coupling. Most importantly, in 6 3 a lignan, two (C C units) are bound through the central carbon of their side chains, 6 3 0 i. e. the 8 and 8 positions (1, 2). The occurrence of C C -dimers, linked at sites other 6 3 0 than the 88 positions, is also known and these compounds have been termed neolignans (3, 4). As these two groups of compounds have close structural as well as biosynthetic relationships, they are often associated together and incorporated under the general term lignan (5). The diverse structural categorization of true lignans and of a few neolignans is presented in Fig. 1. Through the years, several review articles or books covering different facets of lignans, including their ch- istry (6, 7), biogenesis (8), synthesis (9), and biological activities (10) have been published. Enduring research for the investigation of secondary metabolites of plants has evidenced some compounds that are biogenetically related to true lignans or neolignans but bear some features not discerned in conventional lignans. These compounds or groups of compounds have been termed as non-conventional lignans, and include coumarinolignans, ?avonolignans, and stilbenolignans. The non-conventional lignans, like the conventional ones, have two C C units linked 6 3 together but have additional structural features to place them also under the category of coumarins, ?avonoids, or stilbenes.
Natural products chemistrythe chemistry of metabolite products of plants, animals and microorganismsis involved in the investigation of biological phenomena ranging from drug mechanisms to gametophytes and receptors and drug metabolism in the human body to protein and enzyme chemistry. Introduction to Natural Products Chemistry has collected the most important research results of natural product chemistry in China. It overviews the basic principles of isolation, structure, and characteristics of natural products and illustrates current research techniques of structure elucidation with real-life examples of wet chemistry and spectroscopic analyses (UV, IR, MS, and NMR, especially 2d-NMR, HMBC, and HMQC), bioactivity, biosynthesis, and chemical synthesis. Specifically, this book covers: Extraction and isolation of natural products Chemistry of fungal products Alkaloids, sesquiterpenoids, diterpenes, and saponins Amino acids and peptides Flavonoids, anthraquinones, coumarins, and lignans Marine natural products Structural modification of active principles from traditional Chinese medicine Chemical synthesis of natural products Although natural products chemistry has produced enormous results and made great contributions to human health, industry, and agriculture, only a fraction of natural resources have been rigorously studied. Chinese natural products are a gold mine for further exploration with modern technology and methods. This book represents the continuing collaboration between the fields of natural products chemistry, medicine, biology, and agriculture which will continue to discover and implement novel chemical products from natural sources.
