This metabolic pathway is nonexistent in the healthy body, but becomes important after peripheral L-DOPA administration in patients with Parkinson's disease or in the rare cases of patients with AADC enzyme deficiency.
Den här metaboliska vägen existerar inte i en frisk människas kropp, men blir viktig efter L-Dopa administration i patienter med Parkinsons sjukdom eller i sällsynta fall med patienter med AADC enzymbrist.
