This study aims to investigate the effects of medium and long-chain triacylglycerols (MLCT) on lipid composition and lipid metabolism in rat livers in the short term. Male SD rats were randomly divided into Control group, MLCT group, MCT group and HORO group. The rats were fed with oil at the dose of 1 g/100 g body weight per day for 2 weeks. The results showed that compared with HORO group, MLCT significantly decreased the contents of triacylglycerol (TG) and total cholesterol (TC) in plasma, and also decreased low density lipoprotein-cholesterol (LDL-C). MLCT significantly inhibited the increase of liver weight, reduce the contents of TC and TG in livers, and significantly increase the ratio of apolipoprotein Al/ apolipoprotein B. The fatty acid compositions of triacylglycerols and phospholipids in the livers of rats in each group changed greatly, suggesting that the intake of different lipids would lead to changes in the fatty...
