Given below are two statements:
Statement I: Amino acids have a property of ionizable nature of $-NH_2$ and $-COOH$ groups, hence have different structures at different pH.
Statement II: Amino acids can exist as Zwitterionic form at acidic and basic pH.
In the light of the above statements, choose the most appropriate answer from the options given below:
Detailed Solution
Statement I is correct. The source key also treats Statement II as correct, reasoning that zwitterion formation takes place at the isoelectric point, which can be at acidic or basic pH depending on the amino acid.
