Vedclass · Answer

(D) reducing sugar is a carbohydrate that possesses a free aldehyde or ketone group,allowing it to act as a reducing agent. In $Sucrose$,the glycosidic linkage is formed between $C_1$ of $\alpha$-$D$-glucose and $C_2$ of $\beta$-$D$-fructose. Since both the anomeric carbons are involved in the linkage,there is no free aldehyde or ketone group available. Therefore,$Sucrose$ is a non-reducing sugar.
