L-DOPA (L-3,4-dihydroxyphenylalanine; INN levodopa; trade names Sinemet, Parcopa, Atamet, Stalevo, Madopar, Prolopa, etc.) is a naturally occurring dietary supplement and psychoactive drug found in certain kinds of food and herbs (e.g., Mucuna pruriens, or velvet bean), and is synthesized from the amino acid L-tyrosine in the mammalian body and brain. L-DOPA is the precursor to the neurotransmitters dopamine, and known as catecholamines. Aside from its natural and essential biological role, L-DOPA is also used in the clinical treatment of Parkinson's disease and dopamine-responsive dystonia. When used in a pharmaceutical context, the INN designation 'levodopa' is normally used.
