DescriptionECHEMI Editorial ReferenceL-Phenylalanine is an antagonist at α2δ calcium channels with a Ki of 980 nM. IC50 Value: 980 nM [1]Target: Calcium ChannelL-Phenylalanine (LPA) is an electrically neutral amino acid, one of the twenty common amino acids used to biochemically form proteins. In the brain, L-phenylalanine is a competitive antagonist at the glycine binding site of NMDA receptor and at the glutamate binding site of AMPA receptor [2, 3]. At the glycine binding site of NMDA receptor L-phenylalanine has an appa

L-phenylalanine is an odorless white crystalline powder. Slightly bitter taste. pH (1% aqueous solution) 5.4 to 6. (NTP, 1992)|L-phenylalanine is the L-enantiomer of phenylalanine. It has a role as a nutraceutical, a micronutrient, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite, a plant metabolite, an algal metabolite, a mouse metabolite, a human xenobiotic metabolite and an EC 3.1.3.1 (alkaline phosphatase) inhibitor. It is an erythrose 4-phosphate/phosphoenolpyruvate family amino acid, a proteinogenic amino acid, a phenylalanine and a L-alpha-amino acid. It is a conjugate base of a L-phenylalaninium. It is a conjugate acid of a L-phenylalaninate. It is an enantiomer of a D-phenylalanine. It is a tautomer of a L-phenylalanine zwitterion.|Phenylalanine is an essential aromatic amino acid that is a precursor of melanin, [dopamine], [noradrenalin] (norepinephrine), and [thyroxine].|Phenylalanine is an essential aromatic amino acid in humans (provided by food), Phenylalanine plays a key role in the biosynthesis of other amino acids and is important in the structure and function of many proteins and enzymes. Phenylalanine is converted to tyrosine, used in the biosynthesis of dopamine and norepinephrine neurotransmitters. The L-form of Phenylalanine is incorporated into proteins, while the D-form acts as a painkiller. Absorption of ultraviolet radiation by Phenylalanine is used to quantify protein amounts.
