Tyrosine is a polar, non-essential amino acid with a phenolic functionality. L-tyrosine is a natural amino acid that is incorporated into proteins as directed by the genetic code. The phenolic function makes the tyrosine residue in proteins a principle recipient of reactions such as phosphorylation/dephosphorylation important for cell signalling. Tyrosine is also a precursor of various neurotransmitters and hormones.
