Given below are two statements:
Statement I: The structure of Maltose is given below:

Maltose is a non-reducing sugar.
Statement II: The structure of Lactose is given below:

Lactose is a reducing sugar.
In the light of the above statements, choose the correct answer from the options given below
- A Both Statement I and Statement II are true
- B Both Statement I and Statement II are false
- C Statement I is true but Statement II is false
- D Statement I is false but Statement II is true
Answer & Solution
Correct Answer
(D) Statement I is false but Statement II is true
Step-by-step Solution
Detailed explanation
Maltose is a disaccharide composed of two \(\alpha\)-D-glucose units linked by an \(\alpha(1 \rightarrow 4)\) glycosidic bond. The anomeric carbon (C1) of the second glucose unit has a free hemiacetal group, which can open to form an aldehyde. Therefore, maltose can reduce…
