Can tryosine is a aliphatic amino acid?
No, tyrosine is not an aliphatic amino acid. It is actually classified as an aromatic amino acid due to its aromatic ring structure. Aliphatic amino acids do not contain aromatic rings in their side chains.

Which amino acid has a ring?
Histidine is an amino acid that contains an imidazole ring in its side chain. The imidazole ring gives histidine unique chemical properties, making it important in enzyme catalysis and protein structure.
What is an aminobenzoic acid?
Aminobenzoic acid is a compound that consists of a benzene ring with an amino group attached to one position and a carboxylic acid group attached to another position. It is used in some sunscreen formulations due to its ability to absorb UV radiation.
