Question:
Which one of the following amino acids is optically inactive?
Which one of the following amino acids is optically inactive?
Show Hint
Remember that glycine is the only amino acid without a chiral center, making it optically inactive.
Updated On: Jun 18, 2025
- Glycine
- Methionine
- Phenylalanine
- Glutamine
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Glycine is the only optically inactive amino acid. This is because it has two hydrogen atoms attached to its alpha carbon, making it achiral and unable to rotate plane-polarized light.
