The amines involved (acetylcholine, adrenaline, noradrenaline, dopamine, serotonin and histamine) can all act as neurotransmitters in humans. The so-called 'trace amines', used when referring to p-tyramine, beta-phenylethylamine, tryptamine and octopamine, can also bind to recently-discovered GPCRs."^^ .
