Glucose is also a reducing sugar show mutarotation. We can conclude that the Sucrose is not a reducing sugar because it does not have a hydroxyl group in the ring. Hence, sucrose does not show mutarotation. ... They do not have hydroxyl group (−OH)availability at the anomeric position of cellulose.

Which sugar Cannot undergo mutarotation?

Non reducing sugars such as sucrose cannot undergo mutarotation. This is because the glycosidic bond that forms between glucose and fructose in sucrose, eliminates the availability of hydroxyl groups.

Which does not undergo mutarotation?

Due to the absence of free hemiacetal or hemiketal group, sucrose does not exhibit mutarotation.
