Metabolite Identification
Common NameTropine
Descriptiontropine belongs to the class of organic compounds known as tropane alkaloids. These are organic compounds containing the nitrogenous bicyclic alkaloid parent N-Methyl-8-azabicyclo[3.2.1]octane. tropine exists in all living organisms, ranging from bacteria to humans. tropine has been detected, but not quantified in, several different foods, such as japanese chestnuts (Castanea crenata), orange mints (Mentha aquatica), tea leaf willows (Salix pulchra), broccolis (Brassica oleracea var. italica), and muscadine grapes (Vitis rotundifolia). This could make tropine a potential biomarker for the consumption of these foods. tropine is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review very few articles have been published on tropine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Tropine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Tropine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
