Statement I: Maltose is a reducing sugar which gives two moles of D-glucose on hydrolysis
Statement II: Maltose has a 1, 4-\(\beta\)-glucosidic linkage
Answer & explanation
Correct answer: option 3
The correct answer is option 3. Statement I is correct, but Statement II is false.
Statement I: Maltose is a reducing sugar that gives two moles of D-glucose on hydrolysis.
This statement is correct. Maltose is a reducing sugar because it has a free anomeric carbon in the form of an aldehyde group. Upon hydrolysis, maltose is broken down into two moles of D-glucose.
Statement II: Maltose has a 1,4-β-glucosidic linkage.
This statement is false. Maltose actually has an α-1,4-glucosidic linkage. The α-1,4 linkage refers to the configuration of the glycosidic bond between the two glucose molecules.
Therefore, the correct answer is: Statement I is correct, but Statement II is false.
