Chemical Properties

Off-White Solid

Uses

A metabolite of Phenylalanine

Uses

D,L-o-Tyrosine is a precursor in the formation of catecholamines.

Definition

ChEBI: 2-hydroxyphenylalanine is a phenylalanine derivative that is phenylalanine carrying a hydroxy substituent at position 2 on the benzene ring. It is a phenylalanine derivative, a member of phenols and a non-proteinogenic alpha-amino acid.

Biochem/physiol Actions

ortho-Tyrosine (o-Tyrosine), an isomer of standard p-tyrosine, is a phenylalanine oxidation product used as an amino acid oxidation stress marker in analytical procedures such as HPLC and LC-ESI-MS/MS.
