DL- Phenylalanine, or DLPA, is a 50/50 blend of the D- and L-forms of the amino acid phenylalanine(phenylalanine is one of the few amino acids that can be utilized in its D- form). Researchers believe D-phenylalanine (DPA) inhibits the action of an enzyme that breaks down endorphins and enkephalins. These are proteins that bind to opiate receptor ...

L-Phenylalanine, an essential amino acid, is a precursor of the amino acid tyrosine and to 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. L-Phenylalanine is also a direct precursor to PEA (Pheny ...

L-Phenylalanine is an essential, nine-carbon amino acid and is a precursor to the amino acid tyrosine. Because tyrosine is necessary for the synthesis of proteins and the production of the neurotransmitters dopamine and norepinephrine, phenylalanine is an extremely important nutrient that must be obtained through the diet or supplementation. ...
