Abstract:
The sensitivity of carnitine palmitoyltransferase to malonyl-CoA is lost when liver mitochondria are preincubated in a KCl-containing medium. This loss of sensitivity is slowed down in mitochondria from hypothyroid rats and accelerated in mitochondria from fasted and hyperthyroid rats. Glucagon seems to enhance the effect of fasting. The loss of sensitivity is significantly slowed down by 50-500 nM malonyl-CoA and accelerated by small amounts of palmitoyl-CoA in the preincubation medium.
