What naturally occurring amino acid, concentrated in Mucuna pruriens seeds, serves as the direct precursor to the neurotransmitter dopamine?

Answer

L-DOPA (levodopa)

The primary reason for interest in Mucuna pruriens stems from its remarkably high concentration of the naturally occurring amino acid called L-DOPA, also known as levodopa. L-DOPA is fundamentally important because it functions as the direct biochemical precursor for dopamine. Dopamine is a crucial neurotransmitter responsible for regulating motor control, motivation, pleasure, and various hormonal functions within the body. The quantity found in the seeds can range substantially, sometimes accounting for 3% to 9% of the dry weight, which underscores why this specific compound drives much of the scientific and therapeutic investigation into the bean.
