Methyl 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...
متن کاملProduction and Characterization of a New α-Glucosidase Inhibitory Peptide from Aspergillus oryzae N159-1
An α-glucosidase inhibitor was developed from Aspergillus oryzae N159-1, which was screened from traditional fermented Korean foods. The intracellular concentration of the inhibitor reached its highest level when the fungus was cultured in tryptic soy broth medium at 27℃ for five days. The inhibitor was purified using a series of purification steps involving ultrafiltration, Sephadex G-25 gel p...
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 کاملα-d-Tagatopyranose
The title compound, C(6)H(12)O(6), also known as d-Tagatose, occurs in its furanose and pyranose forms in solution, but only the α-pyran-ose form crystallizes out. In the crystal, the molecules form hydrogen bonded chains propagating in [100] linked by O-H⋯O interactions. Further O-H⋯O bonds cross-link the chains.
متن کاملMethyl α-l-rhamnosyl-(1→2)[α-l-rhamnosyl-(1→3)]-α-l-rhamnoside pentahydrate: synchrotron study
The title hydrate, C(19)H(34)O(13)·5H(2)O, contains a vicinally disubstituted tris-accharide in which the two terminal rhamnosyl sugar groups are positioned adjacent to each other. The conformation of the tris-accharide is described by the glycosidic torsion angles ϕ2 = 48 (1)°, ψ2 = -29 (1)°, ϕ3 = 44 (1)° and ψ3 = 4 (1)°, whereas the ψ2 torsion angle represents a conformation from the major st...
