Methyl 3-O-α-d-mannopyranosyl β-d-glucopyranoside tetrahydrate
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 d...
متن کاملMethyl 3-O-α-l-fucopyranosyl β-d-glucopyranoside tetrahydrate
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)°. ...
متن کاملHeterogeneity of Concanavalin A as Detected by Its Binding to p-Nitrophenyl2-O-a-D-Mannopyranosyl-cw-D-mannopyranoside*
The binding of p-nitrophenyl2-O-a-D-mannopyranosyl-a-D-mannopyranoside (MS) to concanavalin A was studied by equilibrium dialysis and uv difference spectroscopy. Concanavalin A, purified by conventional methods, was shown to behave heterogeneously in its interactions with Mz and Sephadex G-75. Elution of concanavalin A bound to Sephadex G-75 by 19 mM Dglucose gives a protein composed predominan...
متن کاملMethyl 3-O-α-l-fucopyranosyl α-d-galactopyranoside: a synchrotron study
The title compound, C(13)H(24)O(10) is the methyl glycoside of a structural element α-l-Fucp-(1→ 3)-α-d-Galp making up two thirds of the repeating unit in the capsular polysaccharide of Klebsiella K63. The conformation of the title compound is described by the glycosidic torsion angles ϕ(H) = 55 (1)° and ψ(H) = -24 (1)°. The hy-droxy-methyl group in the galactose residue is present in the gauch...
