NEETBotanyBiomolecules (B)
Read the following Assertion and Reason and choose the correct option. Assertion: The examples of aromatic amino acids are glutamic acid, lysine and valine. Reason: In solutions of different pH, the structure of amino acid changes.
Options
- ABoth Assertion and Reason are true and Reason is correct explanation of Assertion
- BBoth Assertion and Reason are true but the Reason is not the correct explanation of Assertion
- CAssertion is true but the Reason is false
- DBoth Assertion and Reason are false
Correct answer
D. Both Assertion and Reason are false
Step-by-step solution
There are aromatic amino acids (tyrosine, phenylalanine, tryptophan). A particular property of amino acids is the ionizable nature of –NH2 and –COOH groups. Hence in solutions of different pH, the structure of amino acids changes.
