WebDMT, or N,N-dimethyltryptamine, is a member of a family of organic compounds known as tryptamines. Tryptamines share a core structure consisting of a bicyclic indole heterocycle attached at R 3 to an amino group via an ethyl side chain. DMT contains two methyl groups (CH 3 -) bound to the terminal amine R N at the end of this chain.
