(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.
