Metabolite Identification

Common Name

1-Methylpyrrole

Description

1-Methylpyrrole belongs to the class of organic compounds known as n-methylpyrroles. These are organic heterocyclic compounds containing a N-methylated pyrrole. 1-Methylpyrrole is a herbal, powerful, and smoky tasting compound. 1-Methylpyrrole has been detected, but not quantified in, corns (Zea mays) and tamarinds (Tamarindus indica). This could make 1-methylpyrrole a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 1-Methylpyrrole.
