Chitin Chitosan And Related Enzymes

Chitin, Chitosan, and Related Enzymes documents the proceedings of a four-day joint United States-Japan seminar held at the University of Delaware. The said seminar is aimed to explore the potential of the application of chitin, chitosan, and related products in different scientific fields. The book is divided into six parts. Part I covers the application of chitin and chitosan to pharmaceutical preparations. Part II discusses the applications of chitin and its derivatives. Part III features chitin and chitosan in relation to enzymology and genetic engineering. Respectively covered in Parts IV, V, and VI are the chemical and physical structure of chitin and chitosan; biochemical and physiological properties of chitin and its derivatives; the effects of phosphate on chitin production; and the development of chitin as a suture as well as for orthopedic uses. The text is recommended for biochemists who would like to know more or make further studies about the different applications of chitin, chitosan, and related enzymes.

Biopolymers found in marine animals and plants offer tremendous, largely untapped pharmaceutical potential. Research shows that these biopolymers can be used to combat various infectious as well as inflammatory, oxidative, and carcinogenic factors. Chitin, Chitosan, Oligosaccharides and Their Derivatives: Biological Activities and Applications cove

Chitin presents fundamental information on chitin. The enzymatic processes controlling the synthesis and the breakdown of chitin are discussed, along with its role in the fundamental mechanism of growth, differentiation, nutrition, and movement of a large number of species. This text consists of seven chapters and begins with an overview of chitin research and the rapidly increasing interest in chitin chemistry and applications. The discussion then moves to the enzymatic synthesis of chitin and chitosan and inhibition of chitin biosynthesis, along with the physicochemical characteristics of chitin and chitosan. The chapters that follow focus on chitin chemistry, chitinases and related enzymes, applications of chitin in chromatography, and industrial production and applications of chitin. The final chapter is devoted to medical applications of chitin and its oligomers, from being artificial kidney membranes and antigens against parasites to blood anticoagulants, biodegradable pharmaceutical carriers, wound healing accelerators, and microbiological media. This book will be of interest to biochemists, physicists, industrialists, botanists, entomologists, physiologists, and other scientists in a variety of disciplines, as well as graduate students wishing to undertake research about chitin.

Biopolymers from Renewable Resources is a compilation of information on the diverse and useful polymers derived from agricultural, animal, and microbial sources. The volume provides insight into the diversity of polymers obtained directly from, or derived from, renewable resources. The beneficial aspects of utilizing polymers from renewable resources, when considering synthesis, pro cessing, disposal, biodegradability, and overall material life-cycle issues, suggests that this will continue to be an important and growing area of interest. The individual chapters provide information on synthesis, processing and properties for a variety of polyamides, polysaccharides, polyesters and polyphenols. The reader will have a single volume that provides a resource from which to gain initial insights into this diverse field and from which key references and contacts can be drawn. Aspects of biology, biotechnology, polymer synthesis, polymer processing and engineering, mechanical properties and biophysics are addressed to varying degrees for the specific biopolymers. The volume can be used as a reference book or as a teaching text. At the more practical level, the range of important materials derived from renewable resources is both extensive and impressive. Gels, additives, fibers, coatings and films are generated from a variety of the biopolymers reviewed in this volume. These polymers are used in commodity materials in our everyday lives, as well as in specialty products.

Functional advanced biopolymers have received far less attention than renewable biomass (cellulose, rubber, etc.) used for energy production. Among the most advanced biopolymers known is chitosan. The term chitosan refers to a family of polysaccharides obtained by partial de-N-acetylation from chitin, one of the most abundant renewable resources in the biosphere. Chitosan has been firmly established as having unique material properties as well as biological activities. Either in its native form or as a chemical derivative, chitosan is amenable to being processed—typically under mild conditions—into soft materials such as hydrogels, colloidal nanoparticles, or nanofibers. Given its multiple biological properties, including biodegradability, antimicrobial effects, gene transfectability, and metal adsorption—to name but a few—chitosan is regarded as a widely versatile building block in various sectors (e.g., agriculture, food, cosmetics, pharmacy) and for various applications (medical devices, metal adsorption, catalysis, etc.). This Special Issue presents an updated account addressing some of the major applications, including also chemical and enzymatic modifications of oligos and polymers. A better understanding of the properties that underpin the use of chitin and chitosan in different fields is key for boosting their more extensive industrial utilization, as well as to aid regulatory agencies in establishing specifications, guidelines, and standards for the different types of products and applications.

Exegi monumentum ael'e perennius. The monument I have built will last longer than bronze. Horace My previous book, "Chitin", (1977) was listed by the publisher, as a "key research book", among the most requested books by libraries. It received favorable comments from. each of the journals which reviewed it, Science, 198, 28 Oct. 1977, Physiological Entomology, 2(4), Dec. 1977, The Canadian Institute of Food Science and Technology Journal, April 1978, The Quarterly Review of Biology, 53:361, 1978, Oceanographic Abstracts, 15:182, 1979, Annales de Zoologie-Ecologie Animale, 11:127, 1979, and Enzyme & Microbial Technology, 2, 1980. The variety of these journals testifies to the interdisci plinary character of chitin studies. "Chitin" has really been a landmark, to use the definition given by Science, because it stimulated interest in the less known polysaccharides and in modified chitins, besides chitin itself, to the point that three International Conferences on Chitin / Chitosan were convened (Boston, U. S. A. 1977, Sapporo, Japan 1982 and Senigallia, Italy 1985). In convening the 3rd International Conference on Chitin / Chitosan (1-4 April 1985), one of the main objectives was the preparation of the present book. While the proceedings of the previous two Conferences were very valuable, they did not appear in any book catalogs and this severely Ii mi ted their distribution.
