Cardenal (catolicismo)
The phenylalanine is an Amino-acid aromatic not polar from which is resulting, in particular, the Tyrosine and the Aspartame. Its benzene core confers to him a particular absorption spectrum in U.V, around 260nm wavelength.
Phenylalanine has for Codon S UUC and UUU
It is an essential amino-acid, i.e. that it must be brought by the food, because the organization is unable to synthesize it.
The action of the Phénylalanine hydroxylase transforms it into another amino-acid: the Tyrosin, which is not of this fact not an essential amino-acid.
Industrial chemistry
Phenylalanine is, with the aspartate, one of the two components of the Aspartame, a dipeptide used like sweetening substance in drinks and the food known as “light” (in particular the Coke Cola light) for its capacity sweetening 200 times superior with that of the Saccharose and its low energy value.
Biochemistry
The Phénylcétonurie is a Genetic disease characterized by disorders Comportement with. It must with the progression of a nonefficient version of the enzyme degrading phenylalanine, the Phénylalanine hydroxylase, involving a too high concentration Sang uine at the sick individual.
