L-Phenylalanine is an aromatic organic compound containing amine and acid as functional groups. It is an essential amino acid and its structure can be considered as the derivative of 3-phenylpropionic acid, in which one hydrogen atom present at C-2 position is substituted with amino group. It is a chiral compound and consists of two optical isomers. It is also known as 2-amino-3-phenylpropanoic acid, beta-phenylalanine, L-alfa-amino-beta-phenylpropionic acid, H-Phe-OH and (S)-2-amino-3-phenylpropionic acid.

General Description

  • L-Phenylalanine is an essential amino acid found in several dietary sources, including meat, fish, eggs, cheese, and milk
  • Phenylalanine can be converted into the amino acid tyrosine

Application

  • L-Phenylalanine is used in the synthesis of other amino acids
  • It can be used as a precursor for the skin pigment melanin as well as the monoamine neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline)
  • It is used to biochemically form proteins coded by DNA
  • Due to its ability to absorb ultraviolet radiation, it is used to quantify the amount of protein
  • In research, it is used as an alkaline phosphatase inhibitor
