Research Papers that Mention the Interaction

High Phe concentrations interfere with the production of adrenaline (A), noradrenaline (NA), and dopamine (DA) (1)(3).

The impaired conversion of phenylalanine may affect not only the production of tyrosine but also the biosynthesis of the neurotransmitters dopamine, norepinephrine and epinephrine.

Infusion of epinephrine (plasma concentration: approximately 3600 pmol/L) decreased leucine and phenylalanine and increased ketoisocaproate plasma concentrations and increased the metabolic clearance rate of leucine and phenylalanine.

…,epinephrine induced significant increases in forearm blood flow (P < 0.01) and net lactate … < 0.01) at both 2 and 4 h. At 2 and 4 h phenylalanine release from muscle proteolysis was suppressed (P < 0.01), and at … (P < 0.02), indicating an anticatabolic effect on muscle protein.
