    Tyrosine

Tyrosine (2-Amino-3-(4-hydroxyphenyl) propanoic acid) is an aromatic amino acid. It is a non-polar amino acid with a hydroxyl group. Since it is formed by the hydroxylation of phenylalanine, it is a non-essential amino acid for humans.

Many cellular functions, including cell signalling, are regulated by the phosphorylation of tyrosine residue of the protein kinases. Additionally, tyrosine plays an essential role in the biosynthesis of many biologically important compounds, including neurotransmitters, thyroid hormones and melanin pigments.

In plants, the tyrosine residue of photosystem II acts as an intermediate electron carrier in the oxygen evolution. Natural products synthesis in plants can be stimulated by exogenous phenylamine and tyrosine as these are the primary precursors for secondary metabolites production.

Extraction from plant/animal sources and fermentative production using recombinant E. coli are the established methods for the commercial production of tyrosine.

A combination of caffeine and tyrosine supplementation was shown to improve athletic performance. Due to its cognitive effect, tyrosine could be included in the therapeutic management of Parkinsonís disease.

Seaweeds are a rich source of tyrosine, and the tyrosine content in seaweed exceeds that of soybean.
