2,4,5-Trihydroxy-DL-phenylalanine Chemical Properties, Uses, Production

Uses

6-Hydroxy-DL-DOPA is a catecholamine neurotoxin and endogenous exicitotoxin even at non-NMDA receptors.

Definition

ChEBI: 6-hydroxydopa is a non-proteinogenic alpha-amino acid. It is functionally related to a dopa.

Biochem/physiol Actions

Precursor of the catecholaminergic neurotoxin, 6-hydroxydopamine; converted to 6-hydroxydopamine by L-aromatic amino acid decarboxylase.
