Fatty Acid Metabolism & Ketone Bodies Explained | High Yield Biochemistry USMLE Lecture 10

Master Fatty Acid Metabolism and Ketone Bodies in the simplest and most high-yield way for USMLE Step 1, MBBS, FMGE, NEET PG, PLAB, AMC, NRE and medical school exams. This First Aid Biochemistry lecture covers fatty acid synthesis, beta-oxidation, ketogenesis, ketolysis, the carnitine shuttle, and fatty acid metabolism disorders with clear explanations, mnemonics, and clinical correlations.

Learn how fatty acids are synthesized and broken down, how ketone bodies are produced during fasting and starvation, and why disorders such as carnitine deficiency and MCAD deficiency are frequently tested in board exams. This lecture is designed to help you understand the concepts behind energy metabolism rather than memorize isolated facts.

📌 Topics Covered:
• Fatty Acid Metabolism Overview
• Fatty Acid Synthesis
• Acetyl-CoA Carboxylase (ACC)
• Fatty Acid Synthase Complex
• Malonyl-CoA
• Beta Oxidation of Fatty Acids
• Carnitine Shuttle
• Carnitine Acyltransferase I (CPT-I)
• Ketogenesis
• Ketone Bodies (Acetoacetate, β-Hydroxybutyrate, Acetone)
• Ketolysis
• Fasting & Starvation Metabolism
• Medium-Chain Acyl-CoA Dehydrogenase (MCAD) Deficiency
• Carnitine Deficiency
• High-Yield First Aid Biochemistry Concepts
• USMLE Step 1 Board Review

🔥 Perfect For:
USMLE Step 1, MBBS, BDS, Nursing, FMGE, NEET PG, AMC, PLAB, and all medical students studying metabolism, lipid biochemistry, and energy production pathways.
