The correct Answer is:
To determine which form of amino acid is represented by the structure `NH3^+ - C - COO^-`, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Components**: - The structure consists of an amino group (`NH3^+`), a carbon backbone (`C`), and a carboxyl group (`COO^-`). - The presence of a positively charged amino group and a negatively charged carboxyl group indicates that the molecule has both positive and negative charges. 2. **Understand the Charge Distribution**: - The amino group (`NH3^+`) indicates that it is protonated (gained a hydrogen ion), making it positively charged. - The carboxyl group (`COO^-`) indicates that it has lost a hydrogen ion, resulting in a negative charge. 3. **Define the Zwitterionic Form**: - An amino acid in its zwitterionic form has both a positive and a negative charge but is overall neutral. This occurs due to the ionization of the amino and carboxyl groups. - The zwitterionic form is typically observed at physiological pH (around 7.4), where the amino group is protonated and the carboxyl group is deprotonated. 4. **Conclusion**: - Given the structure `NH3^+ - C - COO^-`, it is clear that this is the zwitterionic form of the amino acid. This form is characterized by the presence of both a positively charged amino group and a negatively charged carboxyl group. ### Final Answer: The structure `NH3^+ - C - COO^-` represents the zwitterionic form of the amino acid. ---
