Maltose, molecular formula C12H22O11, is a disaccharide consisting of two glucose subunits. The principle isomer of maltose is 4-O-α-D-Glucopyranosyl-D-glucose of which both glucoses are the alpha form. Maltobiose or malt sugar is 4-O-alpha-D-Glucopyranosyl-beta-D-glucopyranose which is made up of alpha & beta glucoses. You can use our 3D Model Builder to view & compare both forms of this molecule.
The(1->4) link is the α form since the glycosidic bond to the anomeric carbon, C1 is in the opposite plane from the CH2OH in the same ring on the C6 of the first glucose. When the glycosidic bond to the anomeric carbon, C1, is in the same plane as the CH2OH, it is designated a β(1→4) bond, and the molecule would be maltobiose.
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.
