The pathway would be expected to be similar to that of ethanol as shown in Figure 9.16.
Isopropyl is not much larger than ethanol and so absorption through small pores in the stomach
would seem likely. Distribution would be rapid due to the water solubility of isopropanol. About
10% would be eliminated unchanged, while the remaining 90% would be subject to
dehydrogenation to acetone rather than the aldehyde given that the â€“OH group is on an interior
carbon and not an end carbon. Acetone is water soluble and could be eliminated as is, or there
could be further metabolism in the liver; however, based on the material presented in the text,
this is as far as we can go.
