Identify the carbon atoms of glucose and of fructose forming glycosidic bond in sucrose.
- A C -1 of \(\alpha\)-glucose and \(\mathrm{C}-2\) of \(\beta\)-fructose
- B C -1 of \(\beta\)-glucose and C - 2 of \(\beta\)-fructose
- C C -2 of \(\alpha\)-glucose and C - 2 of \(\beta\)-fructose
- D C -3 of \(\alpha\)-glucose and \(\mathrm{C}-1\) of \(\beta\)-fructose
Answer & Solution
Correct Answer
(A) C -1 of \(\alpha\)-glucose and \(\mathrm{C}-2\) of \(\beta\)-fructose
Step-by-step Solution
Detailed explanation
Structure of sucrose contains glycosidic linkage between \(\mathrm{C}-1\) of \(\alpha\)-glucose and \(\mathrm{C}-2\) of \(\beta\)-fructose. Aldehyde and ketone groups of both the monosaccharide units are involved in formation of the glycosidic bond.
