Foundations of Medical Biochemistry: Molecules, Metabolism, and Signaling

Medical biochemistry provides the molecular language that underlies physiology, pathology, and pharmacology. Sound clinical reasoning rests on a clear understanding of biomolecules, metabolic pathways, and signaling. This foundational course provides that base. By the end of this course you will be able to describe the major biomolecules and their structural principles, outline the central metabolic pathways and their integration, explain principles of cellular signaling, and apply biochemical reasoning to clinical contexts. What you will learn: - The structural and functional principles of amino acids, proteins, carbohydrates, lipids, and nucleic acids - The principles of enzyme function and regulation - The central metabolic pathways including glycolysis, the citric acid cycle, oxidative phosphorylation, and fatty acid oxidation - The integration of metabolism across the fed and fasted states - The principles of cellular signaling including G-protein-coupled receptors and kinase cascades - The biochemical basis of common nutritional and inherited metabolic disorders - Principles of clinical laboratory interpretation grounded in biochemistry The course uses readings, pathway diagrams, clinical correlations, and reflection questions. Each module ends with applied exercises that connect biochemistry to clinical reasoning. This course is written for medical and allied health students, residents reviewing fundamentals, and clinicians refreshing biochemical foundations. By the end you will have replaced fragmented memorization with a structured understanding of medical biochemistry that supports clinical reasoning and laboratory interpretation.
