Question

An example of aromatic amino acid is

• A. Tyrosine
• B. Phenylalanine
• C. Tryptophan
• D. All of these

Answer 1

The correct option is D All of these

Amino acids are the basic units of protein and made up of C, H, O, N and sometimes S. These have one carboxyl group and one amine group on the alpha carbon. Amino acids are amphoteric or bipolar ions or the zwitterions. The aromatic amino acids are the ones that have an aromatic group and benzene ring on their side chain. An example is phenylalanine and tyrosine and tryptophan.

So, the correct option is 'all of these'
