indole

 [in´dōl]
a compound obtained from coal tar and indigo and produced by decomposition of tryptophan in the intestine, where it contributes to the peculiar odor of feces. It is excreted in the urine in the form of indican.

in·dole

(in'dōl), Avoid the misspelling indol.
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.

indole

(ĭn′dōl′)
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.
