Quizplus · Accepted Answer

Phenylalanine is a precursor for the synthesis of neurotransmitters such as dopamine, norepinephrine, and epinephrine, as well as the amino acid tyrosine. However, excessive intake of phenylalanine can inhibit the transport of tryptophan to the brain, which is necessary for the synthesis of serotonin. Therefore, increasing the amount of phenylalanine in the diet may interfere with serotonin synthesis.
