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 Indoles are derivatives of indole where one or more of the hydrogen atoms have been replaced by substituent groups.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 ...
Boar taint is caused by the accumulation of two compounds – androstenone and skatole – in the fat of male pigs. Androstenone (a male pheromone) is produced in the testes as male pigs reach puberty and gives the meat a urine or sweat flavour, while skatole (a byproduct of intestinal bacteria, or bacterial metabolite of the amino acid tryptophan) is produced in both male and female pigs and ...
The indole test is a biochemical test performed on bacterial species to determine the ability of the organism to convert tryptophan into indole. This division is performed by a chain of a number of different intracellular enzymes , a system generally referred to as " tryptophanase ."
The first indole alkaloid, strychnine, was isolated by Pierre Joseph Pelletier and Joseph Bienaimé Caventou in 1818 from the plants of the genus Strychnos. The correct structural formula of strychnine was determined only in 1947, although the presence of the indole nucleus in the structure of strychnine was established somewhat earlier.
