Metabolite Identification
Common Nameindole-3-acetyl-phenylalanine
DescriptionIndole-3-acetyl-phenylalanine is also known as iaa-phe. Indole-3-acetyl-phenylalanine is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Indole-3-acetyl-phenylalanine can be found in a number of food items such as blackcurrant, apricot, common grape, and roselle, which makes indole-3-acetyl-phenylalanine a potential biomarker for the consumption of these food products.
