A week-long intensive lecture course to cover basic subjects in metabolism, including biomolecules, enzymes, glycolysis, citric acid cycle, oxidative phosphorylation, pentose phosphate shunt, photosynthesis, lipid metabolism and amino acid metabolism. The course is most suitable for beginning graduate students who need to learn and/or refresh basic biochemistry in an intuitive and painless manner. The course will emphasize true understanding of basic metabolism, and keep sheer memorization to the minimum. It is expected that students will acquire and retain important knowledge about metabolic biochemistry that would benefit their future research career. The lectures will be interactive and students will work on assigned problem sets and reading assignments each day. Daily problem-solving exams will be given to allow students to self-evaluate the learning process.
