Chapter 18, Problem 18.61UTC

Interpretation Introduction

Interpretation:The sweetener aspartame is made from two amino acids: aspartic acid and phenylalanine.Identify the functional groups in aspartame.

Concept introduction:

The sweetener aspartame is made from two amino acids: aspartic acid and phenylalanine.

Answer to Problem 18.61UTC

Solution:

The functional groups present in aspartame are, -COOH, R-NH₂, $-\text{CO}-\text{NHR}$ , Aromatic, $-\text{R}-\text{COOR}$ .

Explanation of Solution

The structure of the molecule is as follows:

Thus, the functional groups present are as follows:

1. Carboxylic acid (-COOH)
Amine $\left({\text{R-NH}}_{\text{2}}\right)$
2. Amide (primary) $-\text{CO}-\text{NHR}$
3. Aromatic ring
4. Ester $-\text{R}-\text{COOR}$

Conclusion

The functional groups present in aspartame are, -COOH, R-NH₂, $-\text{CO}-\text{NHR}$ , Aromatic, $-\text{R}-\text{COOR}$ .
