| Abstract: | (1→4)-α- and (1→4)-β-D-linked glucosidic oligosaccharide chains were generated by the Monte Carlo method, and the scattering from the systems composed of simulated chains was calculated to compare with the results of small-angle X-ray scattering from the oligosaccharides in aqueous solution. By extending the simulation to a longer chain, a single chain conformation of (1→4)-α- and (1→4)-β-D-linked polysaccharides was evaluated. On the basis of the simulation, the suprastructure of (1→4)-α- and (1→4)-β-D-linked polysaccharides and their gel formation mechanism were discussed in some detail by analyzing the small-angle X-ray scattering from the aqueous solutions of (1→4)-α- and (1→4)-β-D-linked polysaccharides. |
