and two metabolites of 3-methylpentane, 3-methyl-2-pentanol and 3- methyl-3-pentanol [7].It is assumed that the hexane isomers are hydroxylated in man by the cytochrome P- 450 system; the mechanism could be like that known for 2-methylbutane which is oxidized on C-2 to the alcohol by...

Degradation The metabolism of prallethrin was studied following single oral administration and subcutaneous injection of the cis- and trans-isomers to rats at two dose levels and after repeated dosing. The compound was labelled in the alcohol moiety (inferred from the results) (PSD, 1995). Absorp...

Trans- and cis- isomers of fluorocyphenothrin confusingly produce type I and type II effects, respectively. Some pyrethroids, such as fenpropathrin, have been classified as hybrids and appeared to show a mixture of types I and II effects (T and CS). All pyrethroids cause a reduction in ...
Use the Valence Shell Electron Pair Repulsion method to derive the structure and shape of the XeF4. Draw line structures for all 10 of the possible structural (not geometric) isomers of C_6H_8 that do not have 3, 4, or 5 membered ring...
