Tryptamine (Tpm)

Tryptamine is a monoamine alkaloid found in plants, fungi, and animals. It is based around the indole ring structure, and is chemically related to the amino acid tryptophan, from which its name is derived. Tryptamine is found in trace amounts in the brains of mammals and is believed to play a role as a neuromodulator or neurotransmitter.Tryptamine is also the backbone for a group of compounds known collectively as 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.Many if not most plants contain small amounts of tryptamine which is an intermediate in one biosynthetic pathway to the plant hormone indole-3-acetic acid (heteroauxin). Higher concentrations can be found in many Acacia species.
