biogenic amines
Amines found in both animals and plants that are frequently involved in signalling. There are several groups: ethanolamine derivatives include choline, acetylcholine and muscarine; catecholamines include adrenaline, noradrenaline and dopamine; polyamines include spermine; indolylalkylamines include tryptamine and serotonin; betaines include carnitine; polymethyline diamines include cadaverine and putrescine.
