01. Structure of Amino acid and its Properties
Biomolecules

185312 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:

1 Both Statement I and Statement II are correct
2 Both Statement I and Statement II are incorrect
3 Statement I is correct but Statement II is incorrect
4 Statement I is incorrect but Statement II is correct
