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.
