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...
متن کاملDisorder 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...
متن کامل2-Acetamido-2-deoxy-3-O-β-d-galactopyranosyl-d-glucose dihydrate
In the title compound, C(14)H(25)NO(11)·2H(2)O, the primary hydroxyl group connected to the anomeric C atom of the N-acetyl-β-d-glucopyran-ose residue exhibits positional disorder, with occupancy factors for the α and β anomers of 0.77 and 0.23, respectively. The two torsion angles (Φ and Ψ) and the bridge angle (τ) that describe conformation of the glycosidic linkage between the galactopyran-o...
متن کاملSynthesis, Structure and Antioxidant Activity of (Tetra-O-acetyl-β-D-galactopyranosyl)thiosemicarbazones of Substituted Benzaldehydes
Some new substituted benzaldehyde (2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl) thiosemicarbazones were synthesised by reaction of 2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl thiosemicarbazide and different substituted benzaldehydes. The reaction was performed using conventional and microwave-assisted heating methods. The structures of thiosemicarbazones were confirmed by spectroscopic (IR, (1)...
متن کامل1,2,3,4-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...
