This class targets at students with entry-level background in Biochemistry. It serves as refreshment as well as a boost course for those aiming to major in all disciplines in biology. The class starts with covering the chemistry principles that governs protein folding, mechanisms, kinetics and regulation. It then expands on these principles to introduce the structures and metabolisms of carbohydrates and lipids. The second half of the course focuses on introducing the foundation behind membrane functions, energy conversion pathways and the key metabolic pathways.
