Question

Which of the following is the correct structure of L-Glucose ?

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The Correct Option is A

Understanding the Structure of L-Glucose:

L-Glucose is the enantiomer of D-Glucose, which means it has the same structure as D-Glucose but with opposite configurations at each chiral center.
In L-Glucose, the -OH groups are positioned in such a way that it is a mirror image of D-Glucose.

Analyzing the Structure:

For L-Glucose, the configuration of the hydroxyl (-OH) groups should be as follows from top to bottom:

• CHO group at the top.
• -OH on the left for the second, fourth, and fifth carbons.
• -OH on the right for the third carbon.
• CH₂OH group at the bottom.

 

Matching the Correct Structure:

Based on the given configurations, Option (1) matches the structure of L-Glucose.

Conclusion:

The correct structure of L-Glucose is represented by Option (1).
