title: Molecular dynamics simulations of alpha-D-Manp-(1-->3)-beta-D-Glcp-OMe in methanol and in dimethyl sulfoxide solutions.
abstract: Molecular dynamics simulations have been performed of the disaccharide alpha-D-Manp-(1-->3)-beta-D-Glcp-OMe in two different solvents, namely in methanol and in dimethyl sulfoxide. The conformation of the disaccharide is similar to that previously determined in water. The three-dimensional structure around the solute was investigated by geometric hydrogen bonding criteria, radial distribution functions, coordination number analysis, residence times for hydrogen bonds, and spatial distribution functions. Differences and similarities between methanol and the aprotic dimethyl sulfoxide as solvent are analyzed.
