Unusual properties of retinyl palmitate hydrolase activity in rat liver.

open access: yesJournal of Lipid Research, 1979
These studies report the hydrolysis of retinyl palmitate with liver homogenates and homogenate fractions from retinol-depleted rats. The studies utilized an effective in vitro assay for retinyl palmitate hydrolase (RPH) activity, in which microgram ...

Dietary ethanol is associated with reduced lipolysis of intestinally derived lipoproteins.

open access: yesJournal of Lipid Research, 1994
An acute oral fat load produces transient lipemia that is enhanced by the simultaneous ingestion of ethanol. This phenomenon has been reinvestigated in six normal subjects who consumed three different fat loads with and without ethanol.
