WebMetabolism of multiple substrates supports acetyl-CoA production in the fat cell. Glycolysis converts glucose to pyruvate and lactate, providing pyruvate for the TCA cycle. In the mitochondria, pyruvate is converted to acetyl-CoA and enters the TCA cycle by combining with OAA to form citrate. WebSeveral intermediates may leak away from the TCA cycle to form proteins. Citrate may leak away from the TCA cycle to reform acetyl-CoA and OAA in the cytoplasm, with the former entering into lipid biosynthesis. Leaks in the TCA cycle of skeletal muscle fibers are largely replenished through glucose oxidation.
