Two statements, one Assertion (A) and the other Reason (R) are given. Choose the correct option.
Assertion: Maltose, a disaccharide, is a reducing sugar and is obtained by the partial hydrolysis of starch in presence of the enzyme diastase.
Reason: Hydrolysis of one mole of Maltose gives one mole each of \(\alpha-\mathrm{D}-\) Glucose and \(\beta-\) D-Fructose.
- A A is correct but R is wrong.
- B Both A and R are correct and R is the correct explanation of A .
- C Both \(A\) and \(R\) are correct but \(R\) is not the correct explanation of \(A\).
- D \(A\) is wrong but \(R\) is correct.
Answer & Solution
Correct Answer
(A) A is correct but R is wrong.
Step-by-step Solution
Detailed explanation
Maltose is a disaccharide composed of two \(\alpha\)-D-glucose units linked by an \(\alpha(1 \to 4)\) glycosidic bond. Since the anomeric carbon of one glucose unit is involved in the glycosidic linkage while the other remains free, it exhibits mutarotation and acts as a…
