Given below are two statements:
Statement I : Amino acids have a property of ionizable nature of $-\mathrm{NH}_2$ and $-\mathrm{COOH}$ groups, hence have different structures at different $\mathrm{pH}$.
Statement II : Amino acids can exist as Zwitterionic form at acidic and basic $\mathrm{pH}$.
In the light of the above statements, choose the most appropriate answer from the options given below:
Both Statement I and Statement II are correct
Both Statement I and Statement II are Incorrect
Statement I is correct but Statement II is incorrect
Statement I is incorrect but Statement II is correct
Solution
Amino acids can exist in zwitterionic form which contains both positive and negative charges together, thus called Amphoteric molecule. These forms of amino acids, are having both moieties.
