Skatole or 3-methylindole is an organic compound belonging to the indole family. It occurs naturally in the feces of mammals and birds and is the primary contributor to fecal odor. In low concentrations , it has a flowery smell and is found in several flowers and essential oils , including those of orange blossoms , jasmine , and Ziziphus ...
Indole is an organic compound with the formula C 6 H 4 CCNH 3. Indole is classified as an aromatic heterocycle. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered pyrrole ring. Indoles are derivatives of indole where one or more of the hydrogen atoms have been replaced by substituent groups.
The first one consists of the degradation of the amino acid into indole-3-acetate. And in the second step, IAD catalyzes the decarboxylation of the indole-3-acetate to form the final product, skatole. The decarboxylation of indole-3-acetate is chemically difficult since it leaves an unstable carbanion because of the direct elimination of CO 2.
The animal scent is reinforced by the presence of smaller amounts of indole and skatole, which in African civet are present at a concentration of about 1%. [ 1 ] [ 2 ] Uses
Indole-3-acetic acid (IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. [1] IAA is a derivative of indole, containing a carboxymethyl substituent. It is a colorless solid that is soluble in polar organic ...
Fragrance bottles. An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor.For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose.
In addition to volatile sulfur compounds, the heterocyclic compounds indole and skatole (3-Methyl-1H-indole) contribute to the chemical or savory aromas of certain varieties. [16] Skatole in particular was identified as a key contributor to this scent. This compound is found in mammalian feces and is used in the perfuming industry. [17]
The odor associated with flatus is due to hydrogen sulfide, skatole, indole, volatile amines, and short-chain fatty acids also produced by the bacteria. These substances are detectable by olfactory neurons in concentrations as low as 10 parts per billion, hydrogen sulfide being the most detectable. [14]
