CONFORMATIONAL ORIGINS OF POLYSACCHARIDE SOLUTION AND GEL PROPERTIES

摘要: Publisher Summary Chemical structures of polysaccharides are prime importance in determining their properties. Thus, cellulose, a (l → 4)-β- D -glucan, is water insoluble and highly crystalline relation to other polysaccharides. Amylose, (1 4)-α- sparingly soluble water, crystallizes less well than can form rigid thermoreversible gels at low concentration. Dextran, 6)-α- -glucan with small degree branching, extremely non-gel-forming. Polysaccharides show such large differences solubility solution gel properties because great variation chemical the determine shapes molecules adopt both aqueous systems condensed, solid state. widely used industrially phase. This chapter illustrates three different types chain–chain interactions polysaccharide systems. It describes range molecular mechanisms network formation for yield stress solutions.
