  Article Content


Tyrosine (from the Greek tyros, for "cheese", where it was first discovered) is one of the 20 amino acids that are used by cells to synthesize proteins. It plays a key role in signal transduction, since it can be tagged with a phosphate group by protein kinases (phosphorylated) to alter the functionality and/or activity of enzymes. Another important biological function of tyrosine is as a precursor in the synthesis of the thyroid hormone, thyroxin[?].
