WebNow even though all the ATP that's produced by this acetyl-CoA molecule from the oxidation of fatty acids might be fueling this anabolic reaction of gluconeogenesis, because remember anabolic reactions require ATP, this acetyl-CoA molecule in itself has no place to enter this gluconeogenesis pathway. WebFormed from odd-chain fatty acid β-oxidation, this molecule can be carboxylated to form succinyl-CoA. Succinyl-CoA can enter the gluconeogenesis pathway after being converted to oxaloacetate via the TCA cycle. Even-chain fatty acids can only be oxidized to acetyl-CoA, so they cannot be used for gluconeogenesis. Glycerol 3-phosphate:

WebInstead of producing fructose 1,6- bisphosphate as gluconeogenesis does, glyceroneogenesis converts dihydroxyacetone phosphate to glycerol 3-phosphate. ...
