Foundations of Amino Acid Metabolism

Amino acids are the fundamental building blocks of proteins, but managing their synthesis, breakdown, and waste products involves complex, interconnected biochemical systems. This course provides a clear, conceptual foundation in amino acid metabolism, enabling you to trace major pathways, identify key regulatory enzymes, and recognize the metabolic connections that sustain life and health. What you'll learn: * Understand the structural classification and general functions of all essential and non-essential amino acids. * Learn the fundamental mechanisms of protein turnover and the transamination reactions that initiate amino acid catabolism. * Master the principles of the urea cycle, its regulation, and its vital role in detoxifying and excreting excess nitrogen. * Analyze the catabolic pathways for different groups of amino acids, distinguishing between ketogenic and glucogenic fates. * Grasp the significance of one-carbon metabolism (involving folate and B12) in synthesizing essential molecules like nucleotides and specific amino acids. * Apply knowledge of key regulatory steps and enzyme deficiencies that lead to common inherited metabolic disorders. The course begins with core terminology and the basic principles of protein and nitrogen balance before systematically exploring the major anabolic and catabolic routes. We conclude by examining metabolic regulation and clinical relevance. This course is designed for absolute beginners interested in biochemistry, biology, or nutrition. No prior knowledge of advanced chemistry or biology is required. Start reading today and build a strong foundation in metabolic biochemistry.
