Indolamines

Indolamines are a family of neurotransmitters that share a common molecular structure.

Indolamines are a classification of monoamine neurotransmitter, along with catecholamines and ethylamine derivatives.

A common example of an indolamine is the tryptophan derivative serotonin, a neurotransmitter involved in mood and sleep.

In biochemistry, indolamines are substituted indole compounds that contain an amino group.

[citation needed] Indolamines are biologically synthesized from the essential amino acid tryptophan.
