| Eating DMT fails because monoamine oxidase in the gut metabolises the tryptamine into secondary compounds which lack any psychoactivity. |
| The yucca phenotype derives from overexpression of a flavin monooxygenase like enzyme that oxidizes tryptamine to N-hydroxyl-tryptamine in vitro. |
| These include tyramine, tryptamine, phenylethylamine, and serotonin. |
| They suggested that elevations in serotonin and tryptamine were responsible for the clinical symptoms see with this syndrome. |
| Studies of this FMO-like enzyme in yucca revealed that the enzyme most likely catalyzes the oxygenation of the compound tryptamine. |
| The most common biogenic amines found in foods are histamine, tyramine, cadaverine, 2-phenylethylamine, spermine, sperm idi ne, putrescine, tryptamine, and agmatine. |
