D-Phenylalanine is converted into tyrosine and tyrosine in turn is converted into L-dopa, norepinephrine, and epinephrine, three key neurotransmitters. As a result this agent is associated with elevated levels of the neurotransmitters dopamine and norepinephrine in the brain, which may alleviate symptoms of depression. In addition, as an inhibitor of enkephalinase, which metabolizes endorphins, D-phenylalanine may be used to treat chronic pain through blocking the break down of endorphins (natural pain killers)."}]
