Structural Biochemistry is a branch of biochemistry that focuses on understanding the molecular structures of biomolecules such as carbohydrates, proteins, lipids, nucleic acids and enzymes and how these structures determine their functions and interactions in biological systems. It combines principles from chemistry, biology, and physics to study the architecture, dynamics, and mechanisms of biomolecules. This branch is crucial for exploring cellular processes, drug design, and the molecular basis of diseases. The present course serves as an essential guide for understanding how the structures of carbohydrates, proteins, lipids, and other biomolecules are intricately linked to their biological roles in living organisms. This foundational insight prepares students for research and practical applications in biochemistry and related fields.
