During normal liver function, the bile which is produced is transported out of the cells and into the bile duct by special pumps. During Intrahepatic Cholestasis of Pregnancy, the cells are unable to transport the bile out of the cells normally, which leads to bile acids building up in the blood.
Octane is a hydrocarbon and an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3. Octane has many structural isomers that differ by the amount and location of branching in the carbon chain. One of these isomers, 2,2,4-trimethylpentane (isooctane) is used as one of the standard values in the octane rating scale. Octane is a component of gasoline (petrol). As with all low molecular weight hydrocarbons, octane is volatile and very flammable.
Definitions. Reference Fuel â In the measurement of octane quality of gasoline a mixture of two hydrocarbons called iso-octane and normal heptane. Iso-octane is assigned an octane rating of 100, and normal heptane is assigned an octane rating of zero. A blend of 90% iso-octane and 10% n-heptane would have an octane rating of 90 octane. (R + M) / 2 â The average of Research Octane Number and Motor Octane Number; one measure of the combustion quality of gasoline.
