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). The ubiquitous compound can be found in coal tar, tobacco smoke and many foods, especially grilled meats.
Chemical structure of benzo[a]pyrene Chemical structure of benzo[e]pyrene. A benzopyrene is an organic compound with the formula C 20 H 12.Structurally speaking, the colorless isomers of benzopyrene are pentacyclic hydrocarbons and are fusion products of pyrene and a phenylene group.
Benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide is a metabolite of benzo[a]pyrene formed by the introduction of vicinal hydroxyl and epoxide functional groups to the fifth benzene ring. [7] These oxidations are stereoselective , producing the pair of enantiomers with the hydroxyl groups on opposite sides of the pyrene plane and with the epoxide on ...
Dibenz[a,j]anthracene or Benzo[m]tetraphene or 1,2:7,8-Dibenzanthracene is an organic compound with the chemical formula C 22 H 14.It belongs to the class of polycyclic aromatic hydrocarbons (PAHs) and is formed whenever there is incomplete combustion of organic matter.
Pyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a flat aromatic system. The chemical formula is C 16 H 10. This yellow-green solid is the smallest peri-fused PAH (one where the rings are fused through more than one face). Pyrene forms during incomplete combustion of organic compounds. [10]
