Fructose, chemical formula C6H12O6, also known as fruit sugar, is ingested by humans mainly as sucrose, a disaccharide that includes glucose. Its linear form, D-fructose, is a ketose sugar, based on the ketone functional group at carbon 2. Fructose forms beta-d-fructofuranose, a 5 membered ring where the carbon 5 alcohol bonds with carbon 2 to produce an ether functional group.
You can use our 3D Molecular Model Builder to illustrate fructose in its various forms. Choose the model style: "Orbit-flexible" & enter the structure you want to view/build. Simply enter D-fructose for the linear molecule or L-fructose for its optical isomer. View the various ring structures by entering beta-d-fructopyranose or alpha-d-fructopyranose o view 6 member rings; 5 beta-d-fructofuranose or alpha-d-fructofuranose for 5 member rings.
You can also build fructose with our advanced student organic chemistry model set or the class organic chemistry model set. The class biochemistry model set builds the linear version of fructose in the Orbit x-peg style.
You can build any 6 carbon sugar ring with our AtoMag magnetic molecular model. Quickly change the position of any oxygen atom to show different structural isomers; magnetic hydrogens are optional. If you buy two, you can build any disaccharide.
