Descriptions

Application

3,4-Dihydroxy-L-phenylalanine or L-DOPA has been used to stain melanocytes. It has also been used to study its effects on a Drosophila model of Parkinson’;s disease.

Biochem/physiol Actions

3,4-Dihydroxy-L-phenylalanine or L-DOPA is a natural isomer of the immediate precursor of dopamine that crosses the blood-brain barrier. It is used for the treatment of Parkinson’;s disease and is a product of tyrosine hydroxylase.
