Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding Aspartame
Aspartame is a dipeptide formed by the condensation of aspartic acid and phenylalanine. The methyl ester group is added to the carboxyl group of the phenylalanine residue.
Step 2: Structural Features of Aspartame
- Peptide bond: Formed between the carboxyl group of aspartic acid and the amino group of phenylalanine.
- Methyl ester group: Attached to the terminal carboxyl group of phenylalanine.
Step 3: Verifying the Structure
Structure (B) correctly shows the peptide bond between aspartic acid and phenylalanine, with the methyl ester group on phenylalanine.
Conclusion
The correct structure of aspartame is represented by option (B).
