Metabolite Identification
Common Name5-Methoxyindoleacetate
Description5-Methoxyindoleacetate, also known as 5-methoxy-iaa or 5-miaa, belongs to the class of organic compounds known as indole-3-acetic acid derivatives. Indole-3-acetic acid derivatives are compounds containing an acetic acid (or a derivative) linked to the C3 carbon atom of an indole. 5-Methoxyindoleacetate is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 5-Methoxyindoleacetate exists in all living organisms, ranging from bacteria to humans. 5-Methoxyindoleacetate and S-adenosylhomocysteine can be biosynthesized from 5-hydroxyindoleacetic acid and S-adenosylmethionine through the action of the enzyme acetylserotonin O-methyltransferase. In cattle, 5-methoxyindoleacetate is involved in the metabolic pathway called the tryptophan metabolism pathway.
