Isopentane, also called methylbutane or 2-methylbutane, is a branched-chain saturated hydrocarbon (an alkane) with five carbon atoms, with formula C 5 H 12 or CH(CH 3) 2 (C 2 H 5). Isopentane is a volatile and flammable liquid.
Another study found that the perception threshold of 3-mercapto-3-methylbutan-1-ol is 1500 ng/L. [15] This study found that MMB had a "catty" odor, had an orthonasal odor threshold of 2 μg/L in water, and was found in concentrations from 150-1500 μg/kg in coffee. The synthesis of MMB in wine is brought on by the fermentation process.
They are found in meats that are cooked to the "well done" stage, in pan drippings and in meat surfaces that show a brown or black crust.

Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...

PhIP has been found in cooked beef, pork, chicken, and fish products. Exposure to PhIP depends on the eating habits of the individual and can vary up to 5000-fold. Exposure is also related to the type of meat, doneness, cooking method, and quantity consumed. [4] Individual exposures can differ due to various anti-carcinogens in the diet.
