Pentobarbital sleeping time as a readout of hepatic drug metabolism
Pentobarbital sleeping time as a readout of hepatic drug metabolism. Species, exposure and limitations are retained in each linked claim.

How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
Where it participates (unsigned role)
Capsaicin interacted irreversibly with hepatic drug metabolizing enzymes, thereby inhibiting their activity as indicated by prolongation of pentobarbital sleeping time in rats, and such inhibition of drug metabolism was not observed with omega-hydroxycapsaicin; this arm of the study tested capsaicin rather than dihydrocapsaicin.
