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 5, 2024 · Ketone bodies are made when the blood levels of glucose fall very low. Ketone bodies can be converted to acetyl-CoA, which can be used for ATP synthesis via the citric acid cycle. 6.10: Prostaglandin Synthesis The pathway for making prostaglandins is an extension of the fatty acid synthesis pathway.

WebMar 24, 2024 · some are converted to pyruvate, the end product of glycolysis and the start reactant of gluconeogenesis. Hence, these amino acids are glucogenic; some are converted to acetoacetate-CoA and or acetyl-CoA. Both of these can be converted to ketone bodies (acetoacetate/β-hydroxybutyrate) so these are considered ketogenic.
