Which of the following is the linkage between galactose and glucose moieties in a lactose molecule?
Show Hint
Lactose: beta 1-4 linkage.
Galactose \(\beta\)1-4 glucose.
Unique to milk sugar.

Unique to milk sugar.
Updated On: Aug 18, 2026
- Alpha 1-4
- Alpha 2-4
- Beta 2-4
- Beta 1-4
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Lactose is a disaccharide.
It consists of glucose and galactose linked by a specific bond.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the structure of lactose.
Step 3: Detailed Explanation:
Lactose has a beta 1-4 glycosidic linkage.
The bond is between the beta-anomeric carbon of galactose and the 4th carbon of glucose.
Alpha 1-4 is found in starch.
Thus, beta 1-4 is the correct linkage.
Step 4: Final Answer:
The linkage is beta 1-4.
Hence, the correct option is (D). \bigskip
