Biomolecules · Class 12 · JEE Main Previous Year Question
Which of the following statements is not true about sucrose?
- a
On hydrolysis, it produces glucose and fructose.
- b✓
The glycosidic linkage is present between of and of .
- c
It is also named as invert sugar.
- d
It is a non-reducing sugar.
The glycosidic linkage is present between of and of .
Step 1: Exploring Sucrose Facts — Sucrose is also known as cane sugar or invert sugar. It is a non-reducing sugar because its anomeric carbons are both involved in the glycosidic bond.
Step 2: Verifying the Linkage — The glycosidic bond in sucrose connects of an unit to of a unit.
Step 3: Identifying the False Statement — Statement (b) incorrectly claims the bond is between of glucose and of fructose. Thus, (b) is the only not-true statement.
Remember: The linkage is the reason why sucrose lacks a free anomeric position.
