Threonine, Serine, Glycine Catabolism to Pyruvate

The video explores the catabolic pathways of threonine, glycine, and serine, focusing on their degradation to pyruvate and the implications for glucogenic and ketogenic processes. It explains the role of enzymes like threonine dehydrogenase and the glycine cleavage system, highlighting the production of acetyl CoA and NADH. The video also discusses the liver's role in these processes and the importance of gluconeogenesis and ketone body biosynthesis.
