Phenylalanine
What is Phenylalanine ?
Phenylalanine is an essential amino acid that is also one of the aromatic amino acids that exhibit ultraviolet radiation absorption properties and is the most commonly found aromatic amino acid.
It can be converted in the body to tyrosine, which in turn is used to synthesize two important neurotransmitters - dopamine and norepinephrine. It is available in three different forms - L-, D- and DL-. The L- form is the most common and the type in which it is incorporated into the body's proteins. The D- form acts as a painkiller and the DL- a combination of the two.
Why Phenylalanine required ?
It is used in elevating the mood since it is so closely involved with the nervous system, as well as help with memory and learning and has been used as an appetite suppressant.
People suffering from Parkinson's disease It is DLPA (or the D- or L-form alone) is used to treat depression and the D form may also be helpful in the treatment of Parkinson's disease and chronic pain in both osteo-arthritis and rheumatoid arthritis with mixed results increases blood levels of norepinephrine, epinephrine and dopamine - all three required for neurotransmission.
Deficiency of Phenylalanine
Dietary deficiency is rare but symptoms may include lethargy, edema, weakness, skin lesions as well as liver damage and slow growth. A deficiency in diet would only occur with an extremely low protein intake.
Toxicity and symptoms of high intake
Toxicity is rare in dietary intake but large amounts in supplement form may play havoc with your blood pressure and cause headaches, nausea and heartburn. Large amounts of this nutrient may also cause nerve damage.
Some people cannot metabolize phenylalanine and should not take supplementation of this amino acid.
