In humans, catecholamines and phenethylaminergic trace amines are derived from the amino acid phenylalanine.

Tyramine (4-hydroxyphenethylamine; para-tyramine, mydrial or uteramin) is a naturally occurring monoamine compound and trace amine derived from the amino acid tyrosine. Tyramine acts as a catecholamine releasing agent. Notably, it is unable to cross the blood-brain barrier, resulting in only non-psychoactive peripheral sympathomimetic effects. A hypertensive crisis can result, however, from ingestion of tyramine-rich foods in conjunction with monoamine oxidase inhibitors (MAOIs).
