The Correct Option is A
Solution and Explanation
Concept:
Maltose is a disaccharide composed of two glucose units.
The glycosidic bond is formed via condensation between hydroxyl groups of two monosaccharides.
Step 1: Identify structure of maltose. Maltose consists of:
• One \(\alpha\)-D-glucose unit (reducing end)
• One \(\alpha\)-D-glucose unit (non-reducing end linkage)
Step 2: Locate glycosidic linkage. The bond is formed between: \[ C1 \text{ of } \alpha-D-glucose \quad \text{and} \quad C4 \text{ of another } \alpha-D-glucose \] Thus linkage is: \[ \alpha(1\rightarrow4) \]
Step 3: Final conclusion. Correct option: \[ \boxed{A} \]
