dopamineArticle Free Pass dopamine, also called Hydroxytyramine,
a nitrogen-containing organic compound formed as an intermediate
compound from dihydroxyphenylalanine (dopa) during the
metabolism of the amino acid tyrosine. It is the precursor of
the hormones epinephrine and norepinephrine. Dopamine also
functions as a neurotransmitter—primarily by inhibiting the
transmission of nerve impulses—in the substantia nigra, basal
ganglia, and corpus striatum of the brain. A deficiency of
dopamine results in Parkinson’s disease. What made you want to
