Enzymatic Pathways in Neurotransmitter Synthesis: From Tyrosine and Tryptophan to Dopamine, Norepinephrine, and Serotonin Neurotransmitters play a crucial role in brain function and behavior. Among these, dopamine, norepinephrine, and serotonin are particularly significant. This paper examines the enzymatic pathways involved in synthesizing these neurotransmitters from their precursor amino acids, tyrosine and tryptophan. Tyrosine serves as […]
