DSC studies of conformational transitions of multistranded polysaccharides in solution.

Abstract

Multi-stranded structures, which have been found for certain polysaccharides, are stabilized by cooperation of numerous nonbonded interactions between sugar molecules. Since these cooperative structures undergo conformational transitions with changing temperature, information concerning these structures can be obtained by DSC. As a current example, DSC studies of triple helical polysaccharides, (1→6) branched (1→3)-β-D-glucas are presented.
