title: The effect of acute and prolonged ethanol treatment on the contents of coenzyme A, carnitine and their derivatives in rat liver.
abstract: 1. CoA, acetyl-CoA, long-chain acyl-CoA, carnitine, acetylcarnitine and long-chain acylcarnitine were measured in rat liver under various conditions. 2. Starvation caused an increase in the contents of these intermediates, except that of carnitine. 3. A single dose of ethanol had no effect on CoA content, whereas those of acetyl-CoA, acetylcarnitine and carnitine were increased and those of long-chain acyl-CoA and acylcarnitine were decreased. 4. Four weeks' adaptation to ethanol consumption did not change the effect of ethanol administration on these metabolites. 5. It is suggested that ethanol directly increases hepatic fatty acid synthesis and esterification. It is also suggested that this change is reversible and limited to the period of ethanol oxidation. 6. It is demonstrated that ethanol-induced triglyceride accumulation is not related to carnitine deficiency.
