Available in PDF, EPUB and Kindle. Book excerpt: This monograph is concerned with systematization of the infrared spectra of an important natural polymer, cellulose, and its derivatives. The infrared spectra of the main classes of cellulose derivatives are de scribed and interpreted and those of such model compounds as mono-, di-, and trisaccharides are considered. Considerable attention is given to prob lems of technique in obtaining infrared spectra of fibrous cellulose materials, and to the analytical possibilities of infrared spectroscopy in studies of the properties of cellulose and its derivatives. The book will be of use to scientific and plant workers interested in the study and treatment of cellulose, compounds related to cellulose (carbo hydrates and polycarbohydrates), and other polymers. v INTRODUCTION Spectroscopy has nowadays acquired great scientific and practical im portance. Its possibilities are based on the specificity of the emission and ab sorption spectra of all types of material, from elements to complex natural products. Most widely used are the methods of emission spectral analysis (analysis of the emission spectrum from an incandescent body). The rapidity and availability of these methods, together with their high sensitivity and selectivity, has made them indispensable in the practice of plant and scien tific laboratories for establishing the presence of specific elements in a sub stance under investigation.

Download or read book Cellulose Derivatives written by Thomas Heinze and published by Springer. This book was released on 2018-02-12 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes recent progress in cellulose chemistry. The last 10 years have witnessed important developments, because sustainability is a major concern. Biodegradable cellulose derivatives, in particular esters and ethers, are employed on a large scale. The recent developments in cellulose chemistry include unconventional methods for the synthesis of derivatives, introduction of novel solvents, e.g. ionic liquids, novel approaches to regioselective derivatization of cellulose, preparation of nano-particles and nano-composites for specific applications. These new developments are discussed comprehensively. This book is aimed at researchers and professionals working on cellulose and its derivatives. It fills an important gap in teaching, because most organic chemistry textbooks concentrate on the relatively simple chemistry of mono- and disaccharides. The chemistry and, more importantly, the applications of cellulose are only concisely mentioned.

Download or read book Biology and Chemistry of Beta Glucan written by Vaclav Vetvicka and published by Bentham Science Publishers. This book was released on 2013-05-24 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite of the efforts of pharmaceutical researchers to find new medicaments, nature offers many substances with healing properties—beta-glucans belong to this group of compounds. The second volume of the e-book series, Biology and Chemistry of Beta-Glucan, provides new knowledge about these important polysaccharides. In order to understand the role of beta-glucans, it is necessary to control the purity and to determine their composition and structure. This volume presents modern chemical and separation methods which are applied in structural analysis of glucans. As a result of structural analyses, it can be concluded that beta-glucans of different origin vary in chain length, number and types of branching. The book further discusses the biological effects of tailored oligomers and synthetic beta-glucans, including innovative use of enzymatic processes in the synthesis of these compounds. This volume also discusses a hypothesis of beta-glucans’ increasing impact on the photodynamic therapy. In spite of many scientific papers describing the positive role of beta-glucans in protection against diseases, certain epidemiological data suggest that specific illnesses can be related to beta-glucan exposure. The fact of whether or not beta-glucan is an accompanying substance of these biologically active agents is also questioned. Biology and Chemistry of Beta-Glucan: Volume 2 focuses on the strictly scientific basis on the effects of beta-glucan on human health as well as other possibilities of beta-glucan application, such as protection of aquaculture against diseases.
Download or read book Spectroscopy of Biological Molecules New Directions written by Jan Greve and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigation of the structure and function of biological molecules through spectroscopic methods is a field rich in revealing, clever techniques and demanding experiments. It is most gratifying to see that the basic concepts are applied to more and more complex systems, making feasible the study of the behaviour of whole systems in relation to molecular disturbances. The analytical potential of spectroscopy and spectroscopic imaging enables species identification of bacteria and tissue recognition. Clear opportunities for in vivo applications become apparent in the medical field. The methods developed in biophysics start to generate spin-off in the direction of biotechnology, where in previous years we have seen this happen for biochemical techniques. New directions are manifest. Tools are being developed to investigate the behaviour of single molecules in interaction with their environment. Individual interactions can now be investigated and individual molecules in complexes can be visualized. Processes that were previously unobservable as a result of ensemble averaging can now be investigated on a single molecule level. Completely new information with regard to molecular behaviour is obtained in this way. The insights amaze us and the prospect that this development will continue is exciting. The 8th European Conference on the Spectroscopy of Biological Molecules is proud to have contributed to the dissemination of these new directions. This proceedings book is an appropriate reflection of the progress obtained so far in the spectroscopy of biological molecules.
