Possible Interaction: Cysteine and Dihydroxyphenylalanine

Research Papers that Mention the Interaction

Dopa concentrations decreased more rapidly in the presence of cysteine because cysteine addition to dopaquinone prevented reformation of dopa from dopaquinone.
When the concentration of cysteine decreased the cysteinyldopas were rapidly consumed and dopa concentrations increased sharply.
