Chemical Information
FooDB Name3,4-Dihydro-2H-pyrrole
Description1-Pyrroline belongs to the class of organic compounds known as pyrrolines. Pyrrolines are compounds containing a pyrroline ring, which is a five-member unsaturated aliphatic ring with one nitrogen atom and four carbon atoms. 1-Pyrroline exists in all living organisms, ranging from bacteria to humans. 1-Pyrroline is an ammoniacal and shrimp tasting compound. 1-Pyrroline is found, on average, in the highest concentration within grape wine. 1-Pyrroline has also been detected, but not quantified in, several different foods, such as peppermints (Mentha X piperita), lingonberries (Vaccinium vitis-idaea), mollusks, green tea, and roselles (Hibiscus sabdariffa). This could make 1-pyrroline a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 1-Pyrroline.
