WebGlyoxylate condenses with acetyl-CoA (a step catalyzed by malate synthase), yielding malate. Both malate and oxaloacetate can be converted into phosphoenolpyruvate, which is the product of phosphoenolpyruvate carboxykinase, the first enzyme in gluconeogenesis. The net result of the glyoxylate cycle is therefore the production of glucose from ... WebSince we lack those enzymes, the acetyl CoA is converted to ketone bodies to be transported to the brain as a usable respiratory substrate. Acetyl CoA cannot be turned into glucose via gluconeogenesis. If you look at where acetyl CoA enters the citric acid cycle, you’ll see that it happens BEFORE two decarboxylations.
