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[e]pyrene is a polycyclic aromatic hydrocarbon with the chemical formula C 20 H 12. It is listed as a Group 3 carcinogen by the IARC. [1] See also. Benzopyrene;
(like numbers place letters first are omitted while indexing compounds, later on they are added again if necessary) the proper name for this compound is Benzo[a]anthracene. Pyrene: Benzo[a]pyrene, by adding 4 carbon atoms to pyrene the left most ring is the extra one. Benzo[e]pyrene, by adding 4 carbon atoms to the pyrene along its short axis.
One significant compound the bacteria can biodegrade is benzo(a)pyrene (BaP). [13] BaP is a polycyclic aromatic hydrocarbon (PAH), well-known organic pollutant associated with properties of teratogenicity, mutagenicity, and carcinogenicity. BaP is a degradation-resistant compound; thus, it is more inclined to accumulate in the environment. [14]
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 ...
