Metabolite Identification
Common Nameindole-3-acetyl-methionine
DescriptionIndole-3-acetyl-methionine is also known as iaa-met. Indole-3-acetyl-methionine is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Indole-3-acetyl-methionine can be found in a number of food items such as arctic blackberry, garlic, wax gourd, and chicory roots, which makes indole-3-acetyl-methionine a potential biomarker for the consumption of these food products.
