title: Short and long term effects of ethanol on glycerolipid synthesis from palmitate in fasted rat hepatocytes.
abstract: Prolonged ethanol administration to rats increased the rates of glycerolipid synthesis from added [U-14C]palmitate in fasted hepatocytes; this increase was more than 2-fold in triglyceride synthesis. Prolonged ethanol administration to rats completely eliminated the acute ethanol-induced increase in triglyceride synthesis from palmitate in hepatocytes from fasted rats. This adaptive change occurred in a short initial period of about 10 days of ethanol feeding. In hepatocytes from fasted control rats, addition of ethanol produced a rapid and strong increase in the concentration of glycerol 3-phosphate. By contrast, this acute effect of ethanol disappeared in hepatocytes from fasted alcoholic rats after a prolonged--5 weeks--administration of ethanol in a liquid diet.
