Given below are two statements .
Statement I : Maltose has two `alpha`- D-glucose units linked at `C_1` and `C_4` and is a reducing sugar.
Statement II : Maltose has two monosaccharides : `alpha`-D-glucose and `beta` - glucose linked at `C_1` and `C_6` and it is a non-reducing sugar.
In the light of the above statement, choose the correct answer from the options given below :

Options

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 si flase but Statement II is ture.

Explanation

To solve the question regarding the statements about maltose, we will analyze each statement step by step.

### Step 1: Analyze Statement I
**Statement I:** Maltose has two `alpha`-D-glucose units linked at `C_1` and `C_4` and is a reducing sugar.

- Maltose is indeed a disaccharide composed of two `alpha`-D-glucose units.
- These glucose units are linked through a glycosidic bond between the `C_1` of one glucose and the `C_4` of the other glucose.
- Maltose has a hemiacetal group, which means it can donate electrons and thus acts as a reducing sugar.

**Conclusion for Statement I:** This statement is **true**.

### Step 2: Analyze Statement II
**Statement II:** Maltose has two monosaccharides: `alpha`-D-glucose and `beta`-glucose linked at `C_1` and `C_6` and it is a non-reducing sugar.

- This statement is incorrect because maltose does not contain `beta`-glucose; it consists of two `alpha`-D-glucose units.
- Additionally, the linkage mentioned is incorrect; maltose is linked at `C_1` and `C_4`, not `C_1` and `C_6`.
- Since maltose has a hemiacetal group, it is classified as a reducing sugar, not a non-reducing sugar.

**Conclusion for Statement II:** This statement is **false**.

### Final Conclusion
Based on the analysis:
- Statement I is true.
- Statement II is false.

Therefore, the correct answer is that **Statement I is true and Statement II is false**.
