Question

What are the hydrolysis products of Maltose?

• A. \(\alpha\)-D-Glucose + \(\beta\)-D-Fructose
• B. \(\alpha\)-D-Glucose + \(\beta\)-D-Glucose
• C. \(\alpha\)-D-Glucose + \(\alpha\)-D-Glucose
• D. \(\alpha\)-D-Galactose + \(\beta\)-D-Glucose

Hint:

Remember: Maltose = Glucose + Glucose, Lactose = Galactose + Glucose, Sucrose = Glucose + Fructose.

Answer 1

The Correct Option is C

Step 1: Recall the structure of maltose.
Maltose consists of two \(\alpha\)-D-glucose molecules. These glucose units are connected through an \(\alpha(1\rightarrow4)\) glycosidic bond.

Step 2: Hydrolysis of the glycosidic bond.
Upon hydrolysis, the glycosidic linkage breaks and the original monosaccharide units are regenerated. \[ \text{Maltose} + H_2O \rightarrow \alpha\text{-D-Glucose} + \alpha\text{-D-Glucose} \]

Step 3: Eliminate incorrect options.
Glucose + fructose is obtained from sucrose. Galactose + glucose is obtained from lactose. Therefore those options are incorrect.

Step 4: Final answer.
\[ {\alpha\text{-D-Glucose}+\alpha\text{-D-Glucose}} \]
