Question

Which of the following statement is not true about sucrose?

• A. It is also named as invert sugar
• B. The glycosidic linkage is present between $C1$ of $\alpha$ glucose and $C1$ of $\beta$-fructose
• C. It is a non-reducing sugar
• D. On hydrolysis, it produces glucose and fructose

Answer 1

The correct option is B The glycosidic linkage is present between $C1$ of $\alpha$ glucose and $C1$ of $\beta$-fructose

Statement-(b) is not true for sucrose. It is linked through a glycosidic linkage between $C1$ of $\alpha$ glucose and $C2$ of $\beta$-fructose. Since, the reducing groups of glucose and fructose are involved in glycosidic bond formation, sucrose is a non-reducing sugar. On hydrolysis, it produces glucose and fructose
