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: Gluconeogenesis (GNG) is a metabolic pathway that results in the generation of glucose from certain non-carbohydrate carbon substrates. It is a ubiquitous process, present in plants, animals, fungi, bacteria, and other microorganisms. In vertebrates, gluconeogenesis occurs mainly in the liver and, to a lesser extent, in the cortex of the kidneys. It is one of two primary mechanisms – the other being degradation of glycogen (glycogenolysis) – used by humans and many other animal…
