WebCyclic structure of Fructose: Like glucose, fructose also has a cyclic structure. Since fructose contains a keto group, it forms an intramolecular hemiketal. In the hemiketal formation, C5-OH of the fructose combines with C2-keto group. As a result, C2 becomes chiral and thus has two possible arrangements of CH 2 OH and OH group around it. foods to help acid reflux ukFructose 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). electric heater for outsideWebAug 29, 2024 · The cyclic ring of fructose resembles an organic compound called furan, and as such fructose is alternatively named either α-D-fructofuranose or β-D-fructofuranose.
