DOPA and 5 - Hydroxytryptophan are clinically important because______________?
Correct answer: D. They cross Blood Brain Barriers
- A. They are metabolites of various neurogentic amines .Health
- B. They are acidic precursors of Brain amines
- C. They act as neuromodulators
- D. They cross Blood Brain Barriers
Explanation
DOPA and 5-hydroxytryptophan can cross the blood-brain barrier and are then converted to dopamine and serotonin, respectively, within the brain. Their clinical use exploits this transport advantage because dopamine and serotonin themselves cross poorly.
