Abstract
Rates of ketogenesis in mitochondria from fed or starved rats were identical at optimal substrate concentrations, but responded differently to inhibition by malonyl-CoA. Kinetic data suggest that the K1 for malonyl-CoA is greater in the starved animal. These results indicate that, for the regulation of ketogenesis in the starved state, the lower sensitivity of carnitine palmitoyltransferase to inhibition by malonyl-CoA may be more important than the concentration of malonyl-CoA.
