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...

Utilization and metabolism of [U-14C]4' galactosyllactose (O-beta-D-galactopyranosyl-(1----4)-O-beta-D-galactopyranosyl-(1----4)- D-glucopyranose) in rats.

O-beta-D-Galactopyranosyl-(1----4)-O-beta-D-galactopyranosyl- (1----4)-D-glucopyranose (designated as 4'GL) are produced from lactose with Cryptococcus laurentii OKN-4. Excretion and metabolism of 4'GL in rats were examined using a radioisotope technique. [U-14c]4'GL was synthesized from [U-14C]lactose by Cryptococcus laurentii OKN-4. The 14CO2 in expired air was counted after oral administrati...

Disorder and conformational analysis of methyl [beta]-d-galactopyranosyl-(1-->4)-[beta]-d-xylopyranoside

Methyl -d-galactopyranosyl-(1!4)-d-xylopyranoside, C12H22O10, (II), crystallizes as colorless needles from water with positional disorder in the xylopyranosyl (Xyl) ring and no water molecules in the unit cell. The internal glycosidic linkage conformation in (II) is characterized by a ’0 torsion angle (C2Gal—C1 0 Gal—O1 0 Gal—C4Xyl) of 156.4 (5) and a 0 torsion angle (C1Gal—O1 0 Gal—C4Xyl—C3Xyl...

1,2,3,4-Tetra-O-acetyl-beta-D-glucopyranuronic acid monohydrate at 120 K and anhydrous 1,2,3,4-tetra-O-acetyl-beta-D-glucopyranose at 292 K.

The structure of the title acid as the monohydrate, C14H18O11.H2O, displays hydrogen bonding which connects the molecules in layers parallel to (101). In the anhydrous glucopyranose, C14H20O10, only chain connectivity is attained but, due to disorder of the OH group, only partially and in two modes, one less favoured than the other. This provides incomplete connectivity between molecules in cor...
