The title compound, C(13)H(24)O(10)·4H(2)O, is the methyl glycoside of a disaccharide structural element present in the backbone of the capsular polysaccharide from Klebsiella K1, which contains only three sugars and a substituent in the polysaccharide repeating unit. The conformation of the title disaccharide is described by the glycosidic torsion angles ϕ(H) = 51.1 (1)° and ψ(H) = 25.8 (1)°. In the crystal, a number of O-H⋯O hydrogen bonds link the methyl glycoside and water mol-ecules, formin ...[more]
