Metabolite Identification
Common NameIndoleacetic acid
DescriptionIndoleacetic acid, also known as indoleacetate, belongs to the class of organic compounds known as indolyl carboxylic acids and derivatives. Indolyl carboxylic acids and derivatives are compounds containing a carboxylic acid chain (of at least 2 carbon atoms) linked to an indole ring. Indoleacetic acid is a weakly acidic compound (based on its pKa). indoleacetic acid can be biosynthesized from indoleacetaldehyde through the action of the enzyme aldehyde dehydrogenase, mitochondrial. In cattle, indoleacetic acid is involved in the metabolic pathway called the tryptophan metabolism pathway.
