Sucrose molecule model (C12H22O11)
Sucrose, table sugar, is a disaccharide made of one glucose (a pyranose ring) and one fructose (a furanose ring). They are joined through both anomeric carbons by an α(1→2)β glycosidic bond.

What the 3D model of Sucrose shows
The model contains 45 atoms (23 heavy atoms and 22 hydrogens) joined by 46 bonds; in ball-and-stick mode every stick is one bond, and double or aromatic bonds are drawn as multiple sticks. Switch to space-filling to see the molecule as its electron cloud, scaled to van der Waals radii: this is the shape other molecules actually "feel". It can donate 8 and accept 11 hydrogen bonds, and its PubChem XLogP3 of -3.7 means it is very water-loving (hydrophilic). Its topological polar surface area is 190 Ų.

- Excipient in medicines
Interesting facts
- Sucrose is a non-reducing sugar because both anomeric carbons are tied up in the glycosidic bond.
- The enzyme invertase hydrolyses sucrose into glucose and fructose ("invert sugar").
- Sucrose is extracted mainly from sugarcane and sugar beet.

What two sugars make sucrose?
One α-D-glucose and one β-D-fructose, joined by an α(1→2)β glycosidic bond.
Why is sucrose a non-reducing sugar?
Its glycosidic bond links the anomeric carbons of both sugars, so it has no free aldehyde or ketone group.
What is the chemical formula and molar mass of sucrose?
Sucrose is C12H22O11 with a molar mass of 342.3 g/mol (PubChem CID 5988). It contains 45 atoms: 12 carbon, 22 hydrogen, 11 oxygen.
What is the IUPAC name of Sucrose?
The PubChem-computed IUPAC name is (2R,3R,4S,5S,6R)-2-[(2S,3S,4S,5R)-3,4-dihydroxy-2,5-bis(hydroxymethyl)oxolan-2-yl]oxy-6-(hydroxymethyl)oxane-3,4,5-triol.
How do I make a model of Sucrose?
With 45 atoms, Sucrose is a big kit build. Use the interactive model above as your guide, build the ring or core framework first, then add the side groups and finally the hydrogens.
