Identification
Name: L-Tyrosine
Description:Tyrosine (Tyr, Y) or 4-hydroxyphenylalanine is a non-essential amino acid with a polar side group. Its codons are UAC and UAU. Aside from being a proteogenic amino acid, tyrosine has a special role by virtue of the phenol functionality. It occurs in proteins that are part of signal transduction processes. It functions as a receiver of phosphate groups that are transferred by way of protein kinases (so-called receptor tyrosine kinases). Phosphorylation of the hydroxyl group changes the activity of the target protein. (Wikipedia) L-Tyrosine is the enantiomer of tyrosine (the other being D-tyrosine) that is used in building proteins.
