Step 1: Understanding Functional Groups in Amino Acids
- Amino acids contain different functional groups that determine their chemical behavior.
- Basic functional groups include amine (\(-NH_2\)) and imidazole rings.
Step 2: Classification of Given Options
- Arginine, Lysine, and Histidine contain multiple basic groups due to their side chains.
- Asparagine contains only one amine group, making it the correct answer.
Final Answer: Asparagine contains a single amine functional group, making it the correct choice.
The final product in the following reaction Y is:
