The Cellular and Functional Biochemistry course examines the molecular components and chemical processes that occur within cells to provide a comprehensive understanding of their functional organization. It addresses the structure and function of major biomolecules (proteins, lipids, carbohydrates, and nucleic acids), cellular compartmentalization, membrane function, and intracellular signal transduction. This course is intended for third-year undergraduate students in biochemistry. Its main objective is to establish a strong conceptual link between molecular chemistry, cellular mechanisms, and physiological functions.
