Question

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

Evaluating statements about maltose:

Statement I: Maltose has two -D-glucose units linked at C₁ and C₄ and is a reducing sugar — TRUE ✓

- Maltose = -D-glucose + -D-glucose
- Linkage: -1,4 glycosidic bond (C1 of first glucose to C4 of second glucose)
- The second glucose unit has a free anomeric –OH at C1 → maltose is a reducing sugar ✓

Statement II: Maltose has -D-glucose and -D-glucose linked at C₁ and C₆, and is non-reducing — FALSE ✗

Multiple errors:
- Both units are -D-glucose (not  + )
