2-Acetamido-2-deoxy-3-O-β-d-galactopyranosyl-d-glucose dihydrate

In the title compound, C14H25NO11·2H2O, the primary hydroxyl group connected to the anomeric C atom of the N-acetyl-β-d-glucopyranose residue exhibits positional disorder, with occupancy factors for the α and β anomers of 0.77 and 0.23, respectivel...
