Dibenzopyrenes are a group of high molecular weight polycyclic aromatic hydrocarbons with the molecular formula C 24 H 14.There are five isomers of dibenzopyrene which differ by the arrangement of aromatic rings: dibenzo[a,e]pyrene, dibenzo[a,h]pyrene, dibenzo[a,i]pyrene, dibenzo[a,l]pyrene, and dibenzo[e,l]pyrene.
Benzo[a]pyrene (BaP or B[a]P) is a polycyclic aromatic hydrocarbon and the result of incomplete combustion of organic matter at temperatures between 300 °C (572 °F) and 600 °C (1,112 °F).
Related compounds include cyclopentapyrenes, dibenzopyrenes, indenopyrenes and naphthopyrenes.Benzopyrene is a component of pitch and occurs together with other related pentacyclic aromatic species such as picene, benzofluoranthenes, and perylene. [1]
It belongs to the class of organic compounds known as benzo-coumarins or dibenzo-α-pyrones. Its precursors – ellagic acids and ellagitannins – are ubiquitous in nature, including edible plants, such as pomegranates, strawberries, raspberries, walnuts, and others. [2] Urolithin A is not known to be found in any food source.
2-Pyrone 4-Pyrone. Pyrones or pyranones are a class of heterocyclic chemical compounds. They contain an unsaturated six-membered lactone ring, which has one oxygen atom and an adjacent ketone functional group. [1] There are two isomers denoted as 2-pyrone and 4-pyrone.
