Metabolite Identification
Common Name2-Methyl-1-propylamine
Description2-Methyl-1-propylamine, also known as isobutylamine or 1-amino-2-methylpropane, belongs to the class of organic compounds known as monoalkylamines. These are organic compounds containing an primary aliphatic amine group. 2-Methyl-1-propylamine exists in all living organisms, ranging from bacteria to humans. 2-Methyl-1-propylamine is a cheesy and fishy tasting compound. 2-Methyl-1-propylamine is found, on average, in the highest concentration within a few different foods, such as beer, red wine, and white wine. 2-Methyl-1-propylamine has also been detected, but not quantified in, a few different foods, such as black elderberries (Sambucus nigra), common grapes (Vitis vinifera), and french plantains (Musa X paradisiaca). This could make 2-methyl-1-propylamine a potential biomarker for the consumption of these foods. 2-Methyl-1-propylamine is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on 2-Methyl-1-propylamine.
