Book Description
Polysaccharides provides information pertinent to the fundamental aspects of the chemistry of polysaccharides. This book discusses the methods used for the isolation, purification, and structural determination of the various types of polysaccharide. Organized into 14 chapters, this book begins with an overview of the almost universal occurrence of natural macromolecules in living organisms where they form a variety of functions. This text then examines the isolation of polysaccharides, which involves solubilization in aqueous solvents or in dipolar aprotic solvents. Other chapters consider the industrial applications of polysaccharides and of their derivatives. This book discusses as well the procedure for the isolation of wood polysaccharides, which involves the preparation of a holocellulose by the selective solubilization of the lignin. The final chapter deals with the classes of complex natural polymers in which the nature of the linkage of sugar units to other structural units have been established. This book is a valuable resource for biologists.

Book Description
Seaweed Polysaccharides: Isolation, Biological, and Biomedical Applications examines the isolation and characterization of algal biopolymers, including a range of new biological and biomedical applications. In recent years, significant developments have been made in algae-based polymers (commonly called polysaccharides), and in biomedical applications such as drug delivery, wound dressings, and tissue engineering. Demand for algae-based polymers is increasing and represent a potential—very inexpensive—resource for these applications. The structure and chemical modification of algal polymers are covered, as well as the biological properties of these materials – including antithrombic, anti-inflammatory, anticoagulant, and antiviral aspects. Toxicity of algal biopolymers is also covered. Finally, the book introduces and explains real world applications of algal-based biopolymers in biomedical applications, including tissue engineering, drug delivery, and biosensors. This is the first book to cover the extraction techniques, biomedical applications, and the economic perspective of seaweed polysaccharides. It is an essential text for researchers and industry professionals looking to work with this renewable resource. - Provides comprehensive coverage of the research currently taking place in biomedical applications of algae biopolymers - Includes practical guidance on the isolation, extraction, and characterization of polysaccharides from sustainable marine sources - Covers the extraction techniques, biomedical applications, and economic outlook of seaweed polysaccharides

Book Description
fudustrial uses of polysaccharides centre on their ability to thicken or structure many times their own weight of water, or in other words to control the rheology of hydrated systems. Until comparatively recently, however, objective characterisation of polysaccharide rheology, except in a few specialist research laboratories, was largely confined to compression of gels, simple measurements of solution viscosity, often in ill-defined geometries, and imitative tests intended to reflectproductperformance in specific areas ofend-use. Several factors have combined to bring a wider range of rheological techniques into common use. One is the increasing practical importance of systems that cannot adequately be described as solids or liquids, such as 'weak gels' and spreadable pastes. fu parallel, routine characterisation of such systems has become economically feasible with the development of a new generation of comparatively inexpensive computer-controlled instruments. There has also been a change ofemphasis from phenomenologicaldescription ofproduct texture towards the use of rheological measurements to probe the underlying molecular and supramolecular structures and the processes by which they are formed. As a result, even the most pragmatic producers and users of industrial polysaccharides are probably now familiar with terms such as creep compliance, stress overshoot and the ubiquitous G' and G", although perhaps not fully understanding their precise meaning or practical significance. A definitive text giving a rigorous description of the rheological approaches relevant to polysaccharide systems is therefore appropriate and timely. Romano Lapasin and Sabrina Priel are to be congratulated for tackling the daunting but worthwhile taskofproducing such avolume.
