Consider the hydrolysis of . Which of the following statements is true regarding the products formed?
- A.The products are and , both of which are non-reducing sugars.
- B.The hydrolysis results in an equimolar mixture of and , known as invert sugar.
- C.The reaction involves the cleavage of a linkage.
- D.The resulting mixture is dextrorotatory because has a higher specific rotation than .
Show correct answer & step-by-step solution
Correct answer: B — The hydrolysis results in an equimolar mixture of and , known as invert sugar.
Solution
- is a disaccharide composed of and linked by an glycosidic bond.
- Hydrolysis of yields and .
- This mixture is called invert sugar because the sign of optical rotation changes from dextrorotatory to levorotatory.
- Hence the answer is (B).
