Metabolite Identification
Common Name2-Methylpyrrole
Description2-Methylpyrrole belongs to the class of organic compounds known as substituted pyrroles. These are heterocyclic compounds containing a pyrrole ring substituted at one or more positions. 2-Methylpyrrole is found, on average, in the highest concentration within beer. This could make 2-methylpyrrole a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2-Methylpyrrole.
