Abstract
The title compound, C(13)H(24)O(11)·4H(2)O, forms extended hydrogen-bonded networks. These are present between disaccharides, but not as inter-residue hydrogen bonds, as well as to water mol-ecules that in addition form an inter-molecular chain of hydrogen bonds. The conformation of the disaccharide is described by the glycosidic torsion angles ϕ(H) = -34° and ψ(H) = -5°. Macroscopically, the disaccharide was observed to be hygroscopic.
摘要
标题化合物C(13)H(24)O(11)·4H(2)O形成了扩展的氢键网络。这些网络存在于二糖之间，但不是作为残基间氢键，并且还与水分子形成分子间氢键链。二糖的构象由糖苷扭转角ϕ(H)= -34°和ψ(H)= -5°描述。宏观上，观察到二糖具有吸湿性。
