1. basis of many biologically active substances (for example, serotonin, tryptophan); formed in degradation of tryptophan. Synonym(s): ketole
2. Any of many alkaloids containing the indole (1) structure.

n.
1. A white crystalline compound, C8H7N, obtained from coal tar or various plants and produced by the bacterial decomposition of tryptophan in the intestine. It is used in perfumes and as a reagent.
2. Any of various derivatives of this compound.

indole

Chemistry
A heterocyclic compound that is the parent molecule for serotonin tryptophan and other alkaloids; indoles are present in broccoli, cabbage and other cruciferous vegetables, and may have anticarcinogenic activity.

(in'dōl)
1. 2,3-benzopyrrole; basis of many biologically active substances (e.g., serotonin, tryptophan); formed in degradation of tryptophan.
Synonym(s): ketole.
2. Any of many alkaloids containing the indole (1) structure.

indole

2,3-benzopyrrole, an unpleasant-smelling product of protein breakdown that contributes to the odour of the faeces. In high dilution, indole has a pleasant smell and has been used in the perfumery industry. See also SKATOLE.
