tryptamine

[trip´tah-mēn]

a chemical product of the decarboxylation of tryptophan, causing vasoconstriction by the release of norepinephrine at postganglionic nerve endings.

trypt·a·mine

(trip'tă-mēn, -min),

A decarboxylation product of l-tryptophan that occurs in plants and certain foods (for example, cheese). It raises the blood pressure through vasoconstrictor action, by the release of norepinephrine at postganglionic sympathetic nerve endings, and is believed to be one of the agents responsible for hypertensive episodes after therapy with monoamine oxidase inhibitors (for example, pargyline hydrochloride).

According to Strassman (2001), although tissues and organs like the lungs, liver, blood, and eyes all have the enzymes and the biochemical machinery necessary to convert tryptamine to DMT, the pineal gland is particularly rich in them and also has a high amount of serotonin ready to convert to tryptamine: the so-called pineal-DMT hypothesis (Cardena et al., 2015).
