Ketone Body Catabolism

The video explores the biosynthesis and catabolism of ketone bodies, primarily produced by the liver. It discusses their role in energy production, especially in diabetic conditions where glucose is scarce. The catabolic pathway involves enzymes like beta hydroxybutyrate dehydrogenase and thiophorase, leading to the production of acetyl CoA and NADH, which fuel the TCA cycle. The liver, although a producer, cannot catabolize ketone bodies due to the absence of specific enzymes.

What is the significance of the enzyme thiolase in ketone body metabolism?

Why can't the liver catabolize ketone bodies despite producing them?

What are the end products of the catabolism of ketone bodies?
