Conformational analysis of sialyloligosaccharides

Carbohydrate Research, 1991
The conformational properties of several sialyloligosaccharides present as terminal sequences in N- and O-linked carbohydrate groups of glycoproteins, have been analyzed based on the n.m.r. data of selected sialosides. The compounds examined include representatives of the alpha-D-NeuAc-(2----6)-beta-D-Gal-(1----4)-beta-D-GlcNAc, alpha-D-NeuAc-(2----3 ...

Conformational analysis of xyloglucans

International Journal of Biological Macromolecules, 1990
Xyloglucan isolated from the elongating regions of pea stems was examined using X-ray diffraction and energy calculations. The X-ray fibre pattern suggested that the backbone (1----4)-beta-D-glucan takes an extended two-fold helix similar to common cellulose.

Conformational analysis—CI

Tetrahedron, 1974
Abstract It is concluded that the gauche-butane interaction which is one of the cornerstones of conformational analysis has been incorrectly interpreted as to origin, and that the gauche relationship between methyl (or methylene) groups is not the cause of the relative instability of gauche conformations.

Conformational analysis—LXXXIII

Tetrahedron, 1972
Abstract The structures and energies of a number of silanes have been studied by the method of molecular mechanics, and the results are compared with the available experimental data, and with the hydrocarbon analogs. Torsional barriers are relatively small and gauche interactions are unimportant in the silanes, which leads to several unusual ...

Glycine conformational analysis

Journal of the American Chemical Society, 1993
Ab initio quantum mechanical methods, including the self-consistent field (SCF), single and double excitation configuration interaction (CISD), the single and double excitation coupled cluster (CCSD), and the single, double, and perturbative triple excitation coupled cluster [CCSD(T)] have been applied to five C s conformers and four of their C l ...
