WebTransition of acetyl CoA to pyruvate is an irreversible reaction. So acetyl CoA cannot make glucose. The process through which glucose is synthesized from non-carbohydrate sources is called gluconeogenesis. Acetyl CoA can be converted into fatty acids. But fatty acids and ketogenic amino acids cannot be used to synthesize glucose.
