2-Ethyl-5-methoxy-''N'',''N''-dimethyltryptamine (EMDT) is a
tryptamine
Tryptamine is an indolamine metabolite of the essential amino acid, tryptophan. The chemical structure is defined by an indole ─ a fused benzene and pyrrole ring, and a 2-aminoethyl group at the second carbon (third aromatic atom, with the f ...
