    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.
