The 0.4 delta upfield shift and 4-Hz increase in the J1',2' coupling constant for the pyranose anomeric proton in the 1H NMR spectrum is indicative of a pyranose beta-CI conformation in which the aglycon and C-2' and C-4' hydroxyls are equatorial. The mass spectra of trimethylsilylated...

Pyranoses and Furanoses: Some of the mono saccharides can occur in either of two structural configurations: open-chain and cyclic (or ringed). Cyclic forms that contain a six-member ring are called pyranoses and those that contain a five-member ring are called furanoses. Both the open-...
The exclusive presence of β-D-ribofuranose in nucleic acids is still a conundrum in prebiotic chemistry, given that pyranose species are substantially more stable at equilibrium. However, a precise characterisation of the relative furanose/pyranose frac

Remarkably the crystal structure of this protein, solved to 1.2 using x-ray crystallography, revealed that YtfQ binds a single molecule of galactofuranose in its ligand binding pocket. Selective binding of galactofuranose over galactopyranose was also observed using NMR methods that determined the ...
