Metabolite Identification
Common NameLaccarin
DescriptionLaccarin belongs to the class of organic compounds known as pyrrolopyridines. Pyrrolopyridines are compounds containing a pyrrolopyridine moiety, which consists of a pyrrole ring fused to a pyridine. Pyrrole is 5-membered ring consisting of four carbon atoms and one nitrogen atom. Pyridine is a 6-membered ring consisting of five carbon atoms and one nitrogen center. Laccarin has been detected, but not quantified in, a few different foods, such as common mushrooms (Agaricus bisporus), mushrooms, and oyster mushrooms (Pleurotus ostreatus). This could make laccarin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Laccarin.
