## Synopsis A study of the effect of linkage on the possible conformations of di-and polysaccharides of a-D-glucose and also the probable intramolecular hydrogen bonds has been made. The differences in the nature of linkage is shown to effect the energetically preferred conformations; (1 -. , 2) l
## Abstract From Auricularia auricula‐judae, a water soluble β‐D‐glucan, named as AAG, was isolated by extraction with 70% ethanol/water solution. Its chemical structure was analyzed by gas chromatography (GC), gas chromatography‐mass spectrometry (GC‐MS), matrix‐assisted laser desorption /ionizati
The nonbonded interaction energy was computed for xylobiose and xylan as a function of the dihedral angles (+,$). The energy maps indicate that interactions higher than the second neighbor are negligible. Of the four possibilities, the left-handed helical conformation with (+,$) = (63",25") is of th
A chiroptical method of conformational analysis is applied to linear ( 1 + 3 ) -p-D-glucans and the dimeric analogues pand a-laminaribioside. The method is based on a recently developed semiempirical calculational model for saccharide optical activity. We conclude that disaccharide conformational en
