Vedclass · Answer

(A) Mutarotation is the phenomenon of change in optical rotation observed in freshly prepared solutions of reducing sugars. This property is exhibited by sugars that possess a free hemiacetal or hemiketal group,which allows them to exist in equilibrium with their open-chain aldehyde $(-CHO)$ or ketone $(>C=O)$ forms. $(+)$ Sucrose is a non-reducing sugar because its glycosidic linkage is formed between the anomeric carbons of glucose and fructose,leaving no free aldehyde or ketone group. Therefore,$(+)$ Sucrose does not exhibit mutarotation.

Which one of the following does not exhibit the phenomenon of mutarotation?
