WebJul 11, 2024 · 1. As far as I understand, you're correct. Gluconeogenesis and fatty acid oxidation go hand in hand. I think the simple way to understand it is that if glucose and fat are the two main sources of energy available to the liver, it wouldn't make sense to use glucose during gluconeogenesis so the liver uses beta-oxidation of FAs.
