Effect of dietary fat on individual long-chain fatty acyl-CoA esters in rat liver and skeletal muscle.
The effect of dietary fat on the long-chain acyl-CoA ester profile of liver and skeletal muscle was investigated by feeding weanling rats 12%-fat diets composed of high-linoleic safflower oil (73% 18:2n-6), high-oleic safflower oil (70% 18:1n-9) or olive oil (70% 18:1n-9) for six and ten weeks. Approximately 50% of both hepatic and skeletal muscle acyl-CoA esters comprised linoleoyl-CoA or oleoyl-CoA with high-linoleic or oleic feeding, respectively. Total hepatic acyl-CoA ester concentration was 40% higher (p less than 0.05) in rats fed 12% fat compared with controls fed a 4%-fat diet. These data demonstrate that the long-chain acyl-CoA ester profile of liver and skeletal muscle reflects the dietary fatty acid profile.
