The Radiation Chemistry Of Polysaccharides

This publication provides the background and compiles the most recent research findings as well as detailing development activities relating to the development of radiation processed products made of natural polymers. Successes clearly indicate that the radiation processing of natural polymers has emerged as an exciting area where the unique characteristics of these polymeric materials can be exploited for a variety of practical applications in agriculture, healthcare, industry and the environment.

Radiation Chemistry of Carbohydrates is a five-chapter book that deals with the detailed analysis of experimental data on the radiation chemistry of carbohydrates. After introducing the focus of the study, this book discusses the radiation chemistry of water and aqueous solutions. This discussion is followed by a topic on the general approaches and methods of investigation of the radiolysis of carbohydrates. This text also looks into the radiolysis of various classes of carbohydrates and into the major transformations of carbohydrates induced by irradiation. This book will be helpful for students and experts in the field of chemistry and related disciplines.

This monograph—based on the authors course lectures on radiation chemistry of biopolymers—deals with the primary stages of radiation-chemical transformation of main biopolymers. Special attention is given to radiolysis of their aqueous solutions, formation and conversion mechanisms of macroradicals, synthesized in acts of solvent radical interaction with biopolymer molecules and in their natural complexes.

Radiation-Processed Polysaccharides: Emerging Roles in Agriculture is the first book to focus exclusively on this emerging and important option for reducing the overuse and negative impact of agrochemicals in agriculture. Among practices being developed for effective and eco-friendly plant growth regulators in crop production, using radiation-processed polysaccharides (RPPs) is a promising technique. Comprised of chapters from diverse areas of plant science, including agriculture, agronomy, biotechnology, nanotechnology, molecular biology, and radiation agriculture, this book provides insights into the practical application of RPPs and inspires further research toward sustainable and efficient agricultural production. Polysaccharides (sodium alginate, carrageenan, chitosan and others) in their depolymerized state are increasingly important to agriculture based on their unique biological properties, biocompatibility, biodegradability and non-toxicity. Understanding the impact of RPPs on the plant phenotype, translocation of nutrients from source to sink, signal processing, and crosstalk helps improve the applicability of RPPs and sustainable agricultural yield. Presents the latest application of RPPs for improved plant production Includes insights for abiotic stress, biotechnology, nanotechnology and molecular application Explores the efficiency of natural polysaccharides as plant growth promoters

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.
