Which amino acid from following contains \(\text{--CH}_3\) as side chain?
Show Hint
Alanine is the second simplest amino acid after glycine ($R=H$).
Updated On: Apr 26, 2026
- Leucine
- Alanine
- Serine
- Valine
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Identification
Amino acids have a side chain 'R'. - Alanine: $R = -\text{CH}_3$ - Valine: $R = -\text{CH}(\text{CH}_3)_2$ - Leucine: $R = -\text{CH}_2\text{CH}(\text{CH}_3)_2$ - Serine: $R = -\text{CH}_2\text{OH}$
Step 2: Conclusion
Alanine is the amino acid with a methyl side chain.
Final Answer: (B)
Amino acids have a side chain 'R'. - Alanine: $R = -\text{CH}_3$ - Valine: $R = -\text{CH}(\text{CH}_3)_2$ - Leucine: $R = -\text{CH}_2\text{CH}(\text{CH}_3)_2$ - Serine: $R = -\text{CH}_2\text{OH}$
Step 2: Conclusion
Alanine is the amino acid with a methyl side chain.
Final Answer: (B)
