The activity of acyl-CoA: cholesterol acyltransferase in the liver-microsomal fraction was considerably reduced in chicks fed on diet containing unsaturated fat, whereas the activity of HMG-CoA reductase and NADPH cytochrome c reductase was not affected. The fatty acid composition of the microsomes was modified appreciably by this dietary condition and there was no change in the phospholipid or cholesterol levels. The addition of cholesterol to the fat supplemented diet resulted in a considerable increase in the microsomal cholesterol content. A decrease in HMG-CoA reductase and an increase ACAT activity was observed compared with the corresponding values from both the groups fed on a standard diet and a fat supplemented diet with no cholesterol. These results suggest that acyl-CoA: cholesterol acyltransferase is modulated by alteration in the fatty acid composition of the microsomal membrane, while the cholesterol content of the microsomes shows a close relationship with the HMG-CoA reductase activity.
