This book was released on 1991 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Academic dissertation for the degree of Doctor of Philosophy. A biological method based on bioaccumulation and using incubated lake mussels was developed and applied for monitoring organic chlorocompounds originating especially from pulp and paper industry and occuring in the water in very small and fluctuating concentrations. Analysis of bleaching remanants from incubated mussels seemed to be very suitable for the monitoring of organochlorine compounds originating in the pulp and paper industry.
Download or read book Modern NMR Approaches to the Structure Elucidation of Natural Products written by Antony Williams and published by Royal Society of Chemistry. This book was released on 2016-12-14 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ghanian plant Cryptolepis sanguinolenta is the source of a series of fascinating indoloquinoline alkaloids. The most unusual member of this alkaloid series was initially proposed to be a spiro nonacyclic structure, named cryptospirolepine, and was elucidated in 1993 based on the technologies available at that time. There were, however, several annoying attributes to the structure that bothered analysts for the ensuing 22 years. During the two decades that followed the initial work there have been enormous developments in NMR technology. Using new experimental approaches, specifically homodecoupled 1,1- and 1,n-HD-ADEQUATE NMR experiments developed in 2014, the structure of only a 700 µg sample of cryptospirolepine has been revised and is shown on the cover of this volume. The confluence of the NMR technological and methodological advances that allowed the revision of the structure of cryptospirolepine using a submilligram sample seems a fitting example for this book, which is dedicated to the NMR characterization of various classes of natural products. Volume 2 considers data processing and algorithmic based analyses tailored to natural product structure elucidation and reviews the application of NMR to the analysis of a series of different natural product families including marine natural products, terpenes, steroids, alkaloids and carbohydrates. Volume 1 discusses contemporary NMR approaches including optimized and future hardware and experimental approaches to obtain both the highest quality and most appropriate spectral data for analysis. These books, bringing together acknowledged experts, uniquely focus on the combination of experimental approaches and modern hardware and software applied to the structure elucidation of natural products. The volumes will be an essential resource for NMR spectroscopists, natural product chemists and industrial researchers working on natural product analysis or the characterization of impurities and degradation products of pharmaceuticals that can be as scarce as natural product samples.

Available in PDF, EPUB and Kindle. Book excerpt: Determination of Organic Structures by Physical Methods, Volume 6 is a six-chapter text that describes the refinements of some established physical methods for organic structure determination. The opening chapters examine the application of mass spectroscopy to amino acid sequencing of oligopeptides and the computerized organic structure retrieval. The following chapters discuss the historical developments, principles, instrumentation, and application of flash photolysis and 29Si nuclear magnetic resonance to structure determination. A chapter considers the relevant theory from which information on internuclear distances can be obtained and the steady-state measurements, transient methods, as well as the use of Fourier transform technique. This chapter also explores the application of nuclear overhauser effect measurements to structural and stereochemical problems. The concluding chapter deals with the liquid crystal structure determination using NMR spectroscopy. This work will be of value to organic and analytical chemists and researchers.

This book was released on 2021-04-01 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes current understandings and recent progress in four areas: in the first one, the cytochalasans, a group of fungal derived natural products characterized by a perhydro-isoindolone core fused with a macrocyclic ring are shown to exhibit high structural diversity and a broad spectrum of bioactivities. The second one is dedicated to a description of bioactive compounds from the medicinal plants of Myanmar, the third one is dedicated to new structure elucidation techniques in the field of sesquiterpenes. The last one discusses the endogenous natural products that are produced by human cells including endogenous amines, steroids, and fatty acid derived natural products. The co-metabolism and natural product production of the human microbiome is also described including tryptophan, bile acids, choline, and cysteine.

Download or read book NMR Spectroscopy written by Harald Günther and published by John Wiley & Sons. This book was released on 2013-12-13 with total page 842 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear magnetic resonance (NMR) spectroscopy is one of the most powerful and widely used techniques in chemical research for investigating structures and dynamics of molecules. Advanced methods can even be utilized for structure determinations of biopolymers, for example proteins or nucleic acids. NMR is also used in medicine for magnetic resonance imaging (MRI). The method is based on spectral lines of different atomic nuclei that are excited when a strong magnetic field and a radiofrequency transmitter are applied. The method is very sensitive to the features of molecular structure because also the neighboring atoms influence the signals from individual nuclei and this is important for determining the 3D-structure of molecules. This new edition of the popular classic has a clear style and a highly practical, mostly non-mathematical approach. Many examples are taken from organic and organometallic chemistry, making this book an invaluable guide to undergraduate and graduate students of organic chemistry, biochemistry, spectroscopy or physical chemistry, and to researchers using this well-established and extremely important technique. Problems and solutions are included.
