Norepinephrine, a neurotransmitter molecule, is biosynthesized from a natural amino acid. Identify the structure and name of such amino acid. Hint: Draw a carboxylic acid function at the alpha position to the amine and check the backbone to find the most similar amino acid (with an OH in the benzene ring).
