D-Fructose in aqueous solution is a complicated equilibrium of five different tautomeric forms (i.e. α- and β-fructopyranose, α- and β-fructofuranose, and keto-fructose), all of which can rapidly interconvert into each other. The major form is the β-pyranoid tautomer, followed by the β-furanoid isomer; the other compounds play only a minor role in the solution equilibrium. All structures displayed here are global energy-minimum conformations as obtained with the PIMM force-field.
