L-dopa
is a chemical substance that is found naturally in some foods
and is also synthesized by the brain. In the brain,
it is converted into neurotransmitters
including dopamine, as well as
norepinephrine and epinephrine (adrenaline). L-dopa is used
as a medication to treat patients with Parkinson’s
disease, in whom there is a death of dopamine-producing
cells in the substantia nigra
of the brain.
