Ring Structure of Monosaccharides
Ring Structure of Monosaccharides
- Monosaccharides can exist as a linear chain or as ring-shaped molecules.
- The ring shaped is formed in the aqueous solution.
- When the monosaccharides cyclize to form rings, they typically form two types of rings as furanose or pyranose.
- Furanose is a five-membered ring structure.
- Pyranose is a six-membered ring structure.
- In case of aldose sugars, the ring structure is formed when the alcohol group reacts with the aldehyde to produce a hemiacetal.
- In case of ketose sugars, the ring structure is formed when the alcohol group reacts with the ketone to produce hemiketal.
- Both reactions result in the ring-structure with a new asymmetric carbon called the anomeric carbon.
