Chemical Information
FooDB Name5-Acetyl-3,4-dihydro-2H-pyrrole
Description5-Acetyl-3,4-dihydro-2H-pyrrole, also known as 2AP or APR, 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. 5-Acetyl-3,4-dihydro-2H-pyrrole is a strong basic compound (based on its pKa). 5-Acetyl-3,4-dihydro-2H-pyrrole is a sweet, ham, and nut tasting compound. 5-Acetyl-3,4-dihydro-2H-pyrrole has been detected, but not quantified in, cereals and cereal products and tortilla chips. This could make 5-acetyl-3,4-dihydro-2H-pyrrole a potential biomarker for the consumption of these foods.
