Fructose is a 6-carbon polyhydroxyketone. Crystalline fructose adopts a cyclic six-membered structure, called β-d-fructopyranose, owing to the stability of its hemiketal and internal hydrogen-bonding. In solution, fructose exists as an equilibrium mixture of the tautomers β-d-fructopyranose, β-d-fructofuranose, α-d-fructofuranose, α-d-fructopyranose and keto-d-fructose (the non-cyclic form).
