What is DL-Phenylalanine?


Phenylalanine, which is an alpha (essential) amino acid, is found in both naturally occurring (L-phenylalanine) and artificially synthesized (D-phenylalanine) forms. The two different forms of phenylalanine have different medical applications, and the derived DL form has the properties of both, and is, as such, used in the treatment of a number of conditions. As with all phenylalanine, DL-phenylalanine should not be consumed by people with phenylketonuria, a disease which causes the body to be unable to use phenylalanine.




Phenylalanine is an essential amino acid, meaning it is needed by the human body but is not produced by it. Phenylalanine can be found, naturally, in high-protein foods;


L-phenylalanine is also found as a component of aspartame, an artificial sweetener used in products like diet soda and sugar-free gum.


L-phenylalanine is converted by the body into tyrosine, a non-essential amino acid (one that is produced by the body) that is used in the production of chemicals like proteins and hormones, including, according to the University of Maryland Medical center, the neurotransmitters dopamine and epinephrine.


DL-phenylalanine is a combination of this form of phenylalanine; D phenylalanine does is not used in protein synthesis as is its natural form.



Phenylalanine deficiency is linked to a number of symptoms, including, according to Disabled-World.com, confusion, lethargy, and memory problems. Returning the level of phenylalanine to normal should help correct these issues. DL-phenylalanine, in addition to strengthening effects of painkillers for chronic pain sufferers, has been shown, according to Disabled World, to alleviate a number of symptoms associated with Parkinson's disease, including related depression and impaired speech and gait.


DL-phenylalanine, as with other forms of phenylalanine, can negatively impact the health of people who suffer from phenylketonuria (PKU), a disease in which, instead of converting phenylalanine into the useful tyrosine, phenylalanine is converted into phenylpyruvate. Unchecked phenylketonuria can have severe neurological and other health effects, including mental retardation, so phenylketonurics are put on a low-protein, tyrosine-supplemented PKU diet.



1. DL - phenylalanine is a physiological activity of aromatic amino acids, it can't synthesis by human body and animals, it is the important ingredients of formulation of Amino acid

2.In food Industry, DL–phenylalanine can be added in baked foods, improving the flavor of it, and keep our body in amino acid balance.

3.In medicine industry, DL–phenylalanine was the Pharmaceutical intermediates of Styrene-acrylic ampicillin and the important ingredients of adrenaline, thyroxine and melanin.
