Sucrose

Vedclass · Answer

(B) Mutarotation is the change in the optical rotation due to the change in the equilibrium between two anomers when the corresponding stereocenters interconvert.$A$ sugar must have a free hemiacetal or hemiketal group (anomeric carbon) to undergo mutarotation.$Maltose$,$Mannose$,and $Fructose$ are reducing sugars that possess a free anomeric carbon,allowing them to open and close their rings,thus exhibiting mutarotation.$Sucrose$ is a non-reducing sugar because the glycosidic bond is formed between the anomeric carbons of both $Glucose$ and $Fructose$ ($C_1$ of $Glucose$ and $C_2$ of $Fructose$).Since there is no free anomeric carbon available,the ring cannot open,and therefore,$Sucrose$ does not show mutarotation.
