Description
Indole, also called Benzopyrrole, an aromatic heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. It can be produced by bacteria as a degradation product of the amino acid tryptophan. It occurs naturally in human feces and has an intense fecal smell. This off flavour occurs in beer due to contaminant coliform bacteria during the primary fermentation stage of beer brewing. At very low concentrations, however, it has a flowery smell, and is a constituent of many flower scents (such as orange blossoms) and perfumes. Natural jasmine oil, used in the perfume industry, contains around 2.5% of indole. Indole also occurs in coal tar. The participation of the nitrogen lone electron pair in the aromatic ring means that indole is not a base, and it does not behave like a simple amine.Indoles are important precursors for other substances made within the human body and are, therefore, researched and used in lifestyle and medical applications. The compound was officially discovered in 1866 by a scientist working with the properties of zinc dust who reduced oxindole from the zinc dust into an indole. After the discovery, indoles became important constituents of the textile industry, and as more research was conducted, the larger role that indoles played within the human body system was realized. The indolic nucleus in substances like tryptophan and auxin has led to a better understanding of their mechanism within the body.
