High phenylalanine
WebPhenylalanine is an essential amino acid primarily found in dietary protein. Typically, a small amount is utilized for protein synthesis, and the remainder is hydroxylated to tyrosine in an enzymatic pathway that requires phenylalanine hydroxylase (PAH) and the cofactor tetrahydrobiopterin (THB). WebDec 20, 2024 · Excess phenylalanine is toxic to the developing brain and competes with other large neutral amino acids e.g. tryptophan for crossing the blood–brain barrier. Together with deficient tyrosine, this causes marked neurotransmitter derangement, with deficiencies of dopamine, noradrenaline, and serotonin [ 2 ].

WebDescription: L-Phenylalanine, an essential amino acid, is a precursor for the amino acid tyrosine, as well as for a whole series of neurotransmitters and hormones. Phenylalanine is first converted to tyrosine, which becomes L-dopa, which then converts to norepinephrine, a key neurotransmitter and adrenal hormone.
