2-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-glucopyran­ose 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 galactopyran­ose and glucopyran­ose rings are Φ = −81.6 (3)°, Ψ = 118.1 (2)° and τ = 115.2 (2)°. Two water mol­ecules stabilize the mol­ecular packing by forming hydrogen bonds with the saccharide residues.
