Meaning and Definition
An amino acid that is a precursor to important neurotransmitters like dopamine, epinephrine, and norepinephrine.
A naturally occurring biochemical compound (C9H11NO4) involved in dopamine synthesis; also known as DOPA, and used medically (especially in the form levodopa) to treat Parkinson's disease.
Dialectal Variation
