Explanation:
the description of the procedure ensures that when the experiment becomes of a success,specific steps are recorded for improvement of the experiment if maybe the experiment can be done at a short space of time.
Answer:
- Only the methyl ester of aspartame is sweet. True
- Amide bonds can be hydrolyzed under only acidic conditions. False
- The zwitterionic form of the amide bond is the most favored resonance form. True
- The phosphoric acid in soda hydrolyses the aspartame ester making it sweet. False
Explanation:
-
Aspartame is obtained by combining phenylalanine and aspartic acid. Its main impurity is dicetopiperazine, which does not possess sweetening properties.
- Amide bonds can be hydrolyzed both under basic and acidic conditions.
- The zwitterionic form of the amide bond is the most favored resonance form. A zwitterion is an electrically neutral chemical compound, but it has formal positive and negative charges on different atoms, presenting high stability
- Phosphoric acid creates an acidic medium that improves the absorption of carbon dioxide, reducing the pressure generated by carbon dioxide and thus allowing bottleneck. Phosphoric acid has a bitter taste that is offset by the addition of sugar
