"L-phenylalanine, an essential amino acid, is a precursor for the amino acid tyrosine, and a whole series of neurotransmitters and hormones. Phenylalanine is first converted to tyrosine, which becomes l-dopa, which converts to noradrenaline, a key neurotransmitter and an adrenal hormone. L-phenylalanine is also a direct precursor to pea (phenyl-ethylamine), another important neurotransmitter."
