Can acetyl coa be used for gluconeogenesis

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. WebMar 27, 2024 · It is important to note that, acetyl-coA is not an entry point for Gluconeogenesis. The most common reason cited for this is the irreversibility of the enzyme, pyruvate dehydrogenase. Since it is …
