    Journal: Carbohydr Res; 1990 Dec 15; 208():117-26. PubMed ID: 2085806.
    Abstract:
    Conformational studies on beta-D-Xyl-(1----2)-[alpha-D-Man-(1----6)]-beta-D-OMe, beta-D-Xyl-(1----2)-[alpha-D-Man-(1----3)]-beta-D-Man-OMe, and beta-D-Xyl-(1----2)-[alpha-D-Man-(1----3)]-[alpha-D-Man-(1----6)]-beta-D -Man-Ome have been carried out using rotating-frame n.O.e. experiments in combination with HSEA calculations. The estimated time-averaged torsional angles phi and psi about the various glycosidic linkages and the estimated time-averaged rotamer population around the C-5-C-6-linkage of beta-Man in the tetrasaccharide are similar to the corresponding parameters for both trisaccharides.
