Tryptamine is a monoamine alkaloid found in plants, fungi, and animals. It contains an indole ring structure, and is structurally similar to the amino acid tryptophan, from which it derives its name. Tryptamine is found in trace amounts in the brains of mammals and is believed to play a role as a neuromodulator or neurotransmitter.[2]

The tryptamine chemical structure is the backbone for a group of compounds termed collectively tryptamines. This group includes many biologically active compounds, including neurotransmitters and psychedelic drugs.

The concentration of tryptamine in rat brains is about 3.5 pmol/g.[3]
