Abstract
The title compound, C12H22O11·2H2O {systematic name: 6,6′-oxybis[2-(hydroxymethyl)-3,4,5,6-tetrahydro-2H-pyran-3,4,5-triol] dihydrate}, is a disaccharide, which was isolated from Tremella fuciformis. The molecule contains two six-membered rings, both of which adopt a chair conformation. Extensive O—H⋯O hydrogen bonds occur in the crystal structure.
