Dopamine belongs to the family of catecholamines. It is a neurotransmitter. • Hormones, Epinephrine and Norepinephrine (other catecholamines) are derived from Dopamine • Dopamine plays a significant role in learning, goal-directed behavior, regulation of hormones, motor control. DOPAMINE SYNTHESIS Phenylalanine (amino acid from diet) -> phenyalanine hydroxylase -> Tyrosine -> Tyrosine hydroxylase -> DOPA -> Dopa decarboxylase -> Dopamine KEY POINT: Dopamine is synthe...
