Carbohydrates and glycoconjugates play an important role in several life processes. The wide variety of carbohydrate species and their inherent polydispersity and heterogeneity require separation techniques of high resolving power and high selectivity such as high performance liquid chromatography (HPLC) and capillary electrophoresis (HPCE). In the last decade HPLC, and recently HPCE methods have been developed for the high resolution and reproducible quantitation of carbohydrates. Despite the importance of these two column separation technologies in the area of carbohydrates, no previous book describes specialized methods for the separation, purification and detection of carbohydrates and glycoconjugates by HPLC and HPCE.Therefore, the objective of the present book is to provide a comprehensive review of carbohydrate analysis by HPLC and HPCE by covering analytical and preparative separation techniques for all classes of carbohydrates including mono- and disaccharides; linear and cyclic oligosaccharides; branched heterooligosaccharides (e.g., glycans, plant-derived oligosaccharides); glycoconjugates (e.g., glycolipids, glycoproteins); carbohydrates in food and beverage; compositional carbohydrates of polysaccharides; carbohydrates in biomass degradation; etc.The book will be of interest to a wide audience, including analytical chemists and biochemists, carbohydrate, glycoprotein and glycolipid chemists, molecular biologists, biotechnologists, etc. It will also be a useful reference work for both the experienced analyst and the newcomer as well as for users of HPLC and HPCE, graduates and postdoctoral students.

Wir sind umgeben von Kohlenhydraten: der süße Kaffee, Tee oder Dessert, die Stärke als Hauptkomponente unserer Nahrung und die Zellulose als Strukturelement in Pflanzen. Kohlenhydrate sind eine wichtige Klasse biologischer Moleküle, die an einer Anzahl wichtiger biochemischer Prozesse beteiligt sind. Gerade beginnen wir die Rolle von komplexen Zuckern zu verstehen, die an Proteine gebunden die Kommunikation von Zellen in einer "Zuckersprache" bewerkstelligen. Und nicht zuletzt kommen die ersten Kohlenhydratmoleküle als Medikamente auf den Markt. Anders als für andere Biopolymere sind die analytischen Methoden zur strukturellen Charakterisierung und Sequenzanalyse für Kohlenhydrate zur Zeit ungenügend, zum Teil wegen der überwältigenden Isotopenzahl der Zucker. Dieses Buch beschreibt die Entwicklung der letzten Jahre, die mit der Kapillarelektrophorese in Bezug auf eine miniaturisierte Analytik mit besserer Auflösung und Empfindlichkeit gemacht wurden. Instrumentierung, Derivatisierung, Trennbedingungen und Anwendungen in verschiedenen Disziplinen und Industrien wie z. B. Glykobiologie, Lebensmittelindustrie und Biotechnologie werden beschrieben.

Simple carbohydrates, complex oligosaccharides and polysaccharides all belong to a class of ubiquitous (macro)molecules that exhibit a wide range of biological functions, and the recent advent of enhanced enzymatic, chemical and analytical tools used to study these sugars has inaugurated a genuine explosion in the field of glycomics. Specifically, it has led to a deeper understanding of how specific sugar structures modulate cellular phenotypes, and that breakthrough has led to the discovery of new pharmaceuticals for the treatment of many serious diseases, such as cancer. The subsequent rapid expansion of this research holds high promise for future therapeutic regimens, and capillary electrophoresis (CE) refers to the range of related separation techniques that are integral to this vital research. CE uses narrow-bore fused-silica capillaries to separate a complex array of large and small molecules, and Capillary Electrophoresis of Carbohydrates offers a comprehensive look at the latest breakthroughs and improvements in CE and CE techniques applied to monosaccharides up to complex oligosaccharides and polysaccharides. It begins with an overview of the application of CE and CE- mass spectrometric in the analysis of simple carbohydrates without any previous derivatization step before discussing various detection techniques such as spectrophotometric detection, electrochemical detection and other less common techniques. It then covers in detail an array of related topics and numerous applications. It is an essential text for anyone exploring the myriad possibilities of this rapidly expanding field.

This reference describes recent advances and applications of capillary electrophoresis in the field of food science. The first two chapters are devoted to the fundamentals of capillary electrophoresis, and to the main sample preparation techniques used for food analysis using this miniaturized separation technique, respectively. These two introductory chapters are followed by several chapters focused on the different strategies for analyzing specific food components, including lipids, carbohydrates, proteins, peptides, amino acids, vitamins, polyphenols, and food additives. The information provided in these chapters helps readers to understand and develop appropriate methods to carry out a deep characterization of food samples. Relevant concepts such as food authentication, chemical food safety or the control of the quality and safety of dietary supplements, and food metabolomics are also covered, where appropriate. The big potential of capillary electrophoresis to achieve chiral separations and the determination of enantiomers in food samples or to develop targeted and non-targeted metabolomics strategies to ensure food safety and quality is also described. As an additional step towards analytical miniaturization, a chapter devoted to food analysis by microchip electrophoresis is also included in this book. All 14 chapters are contributed by highly experienced researchers in the field. Capillary Electrophoresis in Food Analysis is a key source of information for food chemists and analytical chemists in industry (quality control laboratories) and academia (research labs and training courses).

Shows food analysts ways to use the capillary electrophoresis (CE) technique for the development of new separation methods specifically for food analysis. After describing CE theory and its modes of separation and detection, the authors (food chemistry, University of Reading) walk step by step through the method development process, detailing resolution, stability, and quantification goals. The handbook concentrates on the two most commonly encountered modes of CE--capillary zone electrophoresis and micellar electrokinetic chromatography. Case studies apply CE to the separation of niacin, green tea catechins, and artificial sweeteners and colors in soft drinks. Annotation copyrighted by Book News, Inc., Portland, OR
