Cell Biology - Zellweger Syndrome, Refsum's Disease, Adrenoleukodystrophy

Explore peroxisome structure and function in this 20-minute cell biology lecture. Learn about the normal functions of peroxisomes, including beta-oxidation of very long-chain fatty acids, alpha-oxidation of branched-chain fatty acids, ethanol metabolism, bile acid activation, cholesterol synthesis, plasmalogen synthesis, and catalase activity. Delve into USMLE Step 1 disorders related to peroxisomal deficiencies, focusing on Zellweger syndrome, Refsum's disease, and adrenoleukodystrophy. Gain a comprehensive understanding of these complex cellular processes and their associated disorders through clear explanations and detailed breakdowns of each topic.
