essential amino acid needed for protein and neurotransmitter production
Phenylalanine, often abbreviated as Phe or F, is an essential amino acid that the body cannot produce on its own and must obtain from dietary sources. It plays a crucial role in the production of proteins and other important molecules, including neurotransmitters like dopamine, norepinephrine, and epinephrine. Phenylalanine is also a precursor to tyrosine, another amino acid important for various bodily functions.
