摘要：

MM3(92) was used to study the conformational flexibility of alpha-(1-->2), alpha-(1-->3), and alpha-(1-->6)-linked mannosyl dimers. Mannosyl rings were allowed to relax, and several sets of exo-cyclic orientations were included in the study. Two- and three-dimensional Ramachandran energy representations are similar to those for glucosyl dimers with related linkages. Crystal structures lie in low-energy regions of the maps near local minima. Our results are compared with those presented earlier based on other modeling methods.
