Available in PDF, EPUB and Kindle. Book excerpt: Carbon-13 nuclear magnetic resonance (NMR) spectroscopy, in conjunction with carbon-13 labelling, is a powerful new analytical technique for the study of metabolic pathways and structural components in intact organelles, cells, and tissues. The technique can provide, rapidly and non-destructively, unique information about: the architecture and dynamics of structural components; the nature of the intracellular environment; and metabolic pathways and relative fluxes of individual carbon atoms. With the aid of results recently obtained by us and those reported by a number of other laboratories, the problems and potentialities of the technique will be reviewed with emphasis on: the viscosities of intracellular fluids; the structure and dynamics of the components of membranes; and the primary and secondary metabolic pathways of carbon in microorganisms, plants, and mammalian cells in culture.

Available in PDF, EPUB and Kindle. Book excerpt: In the four decades since its discovery nuclear magnetic resonance (NMR) has become an indispensable tool for obtaining chemical information often. inaccessible by other methods. With the development of instruments of increasingly higher magnetic field strengths, the integration of powerful computers and the availability of an expanding array of flexible software new applications and developments have proliferated rapidly. Among the more exciting new advances is the use of NMR spectroscopy to probe biological systems. The last ten years have witnessed tremendous progress in the development of new NMR imaging and spectroscopic techniques for research and diagnostic applications. The ability to investigate metabolic processes and anatomical structure of intact biological systems under conditions that are totally non-destructive and non-invasive clearly provides much of the impetus for the intense activity that has been generated in the fields of medicine, radiology and the allied basic sciences. Significant advances have been made in this brief period: Whole-body proton NMR imaging today provides anatomical definition of normal and abnormal tissue with a contrast and detection sensitivity often superior to those of X-ray computed tomography and other competing imaging methods. Biochemical pathways, using NMR spectroscopy of protons, carbon-13 and phosphorus-31 nuclei in live animals and man can readily be followed by surface-coil methods to detect metabolites in localized regions. Indicative of the importance and widespread acceptance of these techniques is the explosive growth that the NMR literature is experiencing. This augers well for the future.

Download or read book Nuclear magnetic Resonance in biochemistry written by Thomas James and published by Elsevier. This book was released on 2012-12-02 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear Magnetic Resonance in Biochemistry: Principles and Applications focuses on the principles and applications of nuclear magnetic resonance (NMR) in biochemistry. Topics covered include experimental methods in NMR; the mechanisms of NMR relaxation; chemical and paramagnetic shifts; spin-spin splitting; the use of NMR in investigations of biopolymers and biomolecular interactions; and molecular dynamics in biological and biochemical systems. This text is comprised of eight chapters; the first of which gives an overview of NMR spectroscopy and its use in studies of biological systems. The next two chapters discuss the theoretical basis for NMR applications in biochemistry, with emphasis on Bloch equations, quantum mechanics, correlation function and correlation time, double resonance, and chemical exchange. The reader is then introduced to the basis for chemical shifts and spin-spin splitting, along with several examples of the use of these NMR parameters in studies of small molecule interactions and structure. The experimental apparatus and procedures employed in NMR studies, Fourier transform NMR, and NMR spectral parameters of small molecules interacting with macromolecules are also considered. The book highlights the information obtainable from the spectra of biopolymers, and then concludes with a chapter on NMR investigations of the state of motion of lipids in membranes and model membranes; water in macromolecular and cellular systems; and sodium ion in biological tissue. This book is intended primarily for chemists, biochemists, biophysicists, and molecular biologists, as well as graduate students.

This book was released on 2006-08-05 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: ‘‘Biopolymers’’ are polymeric materials of biological origin, including globular, membrane, and fibrous proteins, polypeptides, nucleic acids, po- saccharides, lipids, etc. and their assembly, although preference to respe- ive subjects may be different among readers who are more interested in their biological significance or industrial and/or medical applications. Nevert- less, characterizing or revealing their secondary structure and dynamics may be an equally very important and useful issue for both kinds of readers. Special interest in revealing the 3D structure of globular proteins, nucleic acids, and peptides was aroused in relation to the currently active Structural Biology. X-ray crystallography and multidimensional solution NMR sp- troscopy have proved to be the standard and indispensable means for this purpose. There remain, however, several limitations to this end, if one intends to expand its scope further. This is because these approaches are not always straightforward to characterize fibrous or membrane proteins owing to extreme difficulty in crystallization in the former, and insufficient spectral resolution due to sparing solubility or increased effective molecular mass in the presence of surrounding lipid bilayers in the latter.

Available in PDF, EPUB and Kindle. Book excerpt: We are pleased to present this second volume of a series that has already received much interest. The application of magnetic resonance methods to the study of actual biological systems as contrasted to cell-free samples, although not entirely novel, as demonstrated by Civan and Shporer in Volume I, has taken on new dimensions with the use of phosphorus-31 and carbon-13 NMR in studying cells, tissues, and organelles. The applications of 31 P NMR to such systems is reviewed in this volume, while carbon-13 will be covered in a later one. The use of nitroxide spin labels has grown to the point where it now may be considered a common biological technique. The synthesis and applications of a new class of nitroxides is described in this volume. ESR spectroscopy of paramagnetic ions is a powerful approach to studying molecular and structural details, as the chapter by Boas, Pilbrow, and Smith on the ESR of copper in Volume 1 has shown. In this volume the ESR of molybdenum and iron is treated in a comparable fashion. In the first volume some aspects of 1 H NMR spectroscopy of certain classes of In this volume the high-resolu biological macromolecules were discussed.· tion multinuclear NMR spectra of peptides, including the physiologically significant peptide hormones, are reviewed.

This book was released on 2012-12-06 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through numerous conversations with other synthetic chemists it became apparent that the great power of carbon nuclear magnetic resonance was being significantly underutilized. In our own work we have found that 13C spectroscopy is a more powerful tool than IH NMR spectroscopy, especially for probing subtle stereochemical questions in complicated systems. This is especially true in five membered ring compounds where IH NMR is at a particular disadvantage. The two techniques can be used independently to solve the same question-that of stereochemistry - but they do so in different ways. Advantage can be taken in IH NMR of a relatively consistent relationship between stereochemical orientation and coupling constants between vicinal protons, while in 13C NMR it is the correlation between spatial relationships of non-hydrogen, y substituents and their effect on chemical shift that can be used to assign stereochemistry. It was also clear that the use of 13C NMR required a different approach to problem solving than that typically used with IH NMR. While the latter technique could be employed with a very general approach (e.g., the Karplus equation), 13C NMR would, at least for the immediate future, require a relatively extensive set of model systems from which the consequences of stereochemical changes could be derived for any given carbon framework.
Download or read book Fundamentals of Protein NMR Spectroscopy written by Gordon S. Rule and published by Springer Science & Business Media. This book was released on 2005-10-28 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: NMR spectroscopy has proven to be a powerful technique to study the structure and dynamics of biological macromolecules. Fundamentals of Protein NMR Spectroscopy is a comprehensive textbook that guides the reader from a basic understanding of the phenomenological properties of magnetic resonance to the application and interpretation of modern multi-dimensional NMR experiments on 15N/13C-labeled proteins. Beginning with elementary quantum mechanics, a set of practical rules is presented and used to describe many commonly employed multi-dimensional, multi-nuclear NMR pulse sequences. A modular analysis of NMR pulse sequence building blocks also provides a basis for understanding and developing novel pulse programs. This text not only covers topics from chemical shift assignment to protein structure refinement, as well as the analysis of protein dynamics and chemical kinetics, but also provides a practical guide to many aspects of modern spectrometer hardware, sample preparation, experimental set-up, and data processing. End of chapter exercises are included to emphasize important concepts. Fundamentals of Protein NMR Spectroscopy not only offer students a systematic, in-depth, understanding of modern NMR spectroscopy and its application to biomolecular systems, but will also be a useful reference for the experienced investigator.

Download or read book High Resolution NMR Spectroscopy written by Krystyna Kamieńska-Trela and published by Elsevier Inc. Chapters. This book was released on 2013-06-08 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter is devoted to the 1–3JCCs and to the factors influencing their magnitude. The experimental and calculated J data presented in the subsequent parts of the chapter are arranged with the thought of showing how hybridization, substituent electronegativity, the complex and hydrogen bond formation, and geometry of the compound bear on the JCC magnitude and which range of changes can be expected for a given type of coupling when all these effects are taken into account. The subsequent sections are devoted to the couplings across single, double, and triple CC bonds and to the couplings in aromatic and heteroaromatic systems and in the compounds of biological importance. It is also shown that at the present level of theory, it is possible in many cases to reproduce the experimental J values very exactly, achieving one-to-one correspondence.
