Polysaccharides — Syntheses, Modifications and Structure/Property Relations (Studies in Organic Chemistry, Vol. 36) (original) (raw)

1989, Bioelectrochemistry and Bioenergetics

This book contains the following chapters: Structures, General p01~;accharide methods, Their properties, Syntheses of new carbohydrate polymers, Polysaccharide analogues and conjugates, Substitution patterns of polysaccharidc derivatives, Chemical modifications, Enzymatic modifications, Alterations of polysaccharide integrity and &ctroch~mical modifications, Relationships between structure and properties, Subject index. The broadest parts of this state-of-the-art monograph are the chapters on "Chemical modifications" and "Relationships between structure and properties". Starting with natural polysaccharides such as alginates, pectins, carrageenans, agarose, cellulose, starch, etc., synthetic analogues are described, Besides modifications by reduction, oxidation, esterification, etherification, N-alkylation, deamination, halogen &on, copolymerisation., etc., physical chemical me+bods for the determination of structures (e.g. NMR, ESR, MS, fluor&cence spectroscopy) and substitutions as well as for depolymerisation (shear degradation, ultrasonic and radical-mediated destruction) and thermochemical and electrochemical modifications are discussed in detail. As regards important relationships, the following changes of the primary and secondary structure are taken into account: hydrogen bonding, gel-forming tendency, solvent influence, interactions with salts, surfactants, proteins, etc. Each chapter is followed by a comprehensive list of references extending up to 1987) increasing the usefulness of this book as a information for everybody interested in polysaccharides.
