L-Phenylalanine, an essential amino acid, is a precursor of 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 norepinephrine, a key neurotransmitter and an 
adrenal hormone. L-Phenylalanine is also a direct precursor of PEA 
(phenylethylamine), another important neurotransmitter.
