Application

L-Tyrosine has been used to prepare tyrosine solution for tyrosinase assay. It has also been used to assay pepsin activity.

Biochem/physiol Actions

L-Tyrosine is a non-essential amino acid with a polar side chain. It is utilized by cells to synthesize proteins that have a role in signal transduction. L-Tyrosine is a proteogenic amino acid that acts as a receiver of phosphate groups that are transferred by kinases.
