One enzyme responsible for breaking down these chemicals has a notable V158M mutation that renders it heat-sensitive, and that enzyme is inhibited by enterocapone. Leukochromes and o-quinones are oxidation products of these chemicals.

Cells that produce these chemicals take up a radioactive MIBG tracer, and their breakdown products include MHBG and vanillylmandelic acid. The ventral tegmental area and locus coeruleus produce these chemicals, which are degraded by the action of COMT. A tumor known for being ten percent bilateral and ten percent malignant periodically produces them, causing flushing and blood pressure spikes; that tumor is known as a pheochromocytoma. MAO is responsible for breaking these chemicals down, and they are produced by tyrosine hydroxylase in the chromaffin cells of the medulla of a certain gland. For 10 points, name these chemicals, some of which are secreted from the adrenal gland, which include dopamine, epinephrine and norepinephrine.
