1. Biochemistry Lecture 1

2. Bloom’s Taxonomy Richard C. Overbaugh, Lynn Schultz Old Dominion University

3. Student Objectives for this course Calculate bioenergetic parameters and evaluate carbon molecules reactions Reproduce and explain key metabolic processes: glycolysis, TCA cycle, electron transport and oxidative phosphorylation, fatty acid oxidation Analyze protein structure and function and evaluate different methods used to assess and test structure and function Trace key metabolites through key pathways, design experiments to test carbon flux Compare and contrast modes of metabolism regulation and judge the effects of different modes

4. Biochemistry is the chemistry of Living Systems The Chemistry of Carbon and Water Themes for this course: –The transformation of energy –Levels of complexity

5. Cells

7. Levels of Complexity Lipids

8. The Inner Life of the Cell http://multimedia.mcb.harvard.edu/anim_innerl ife.htmlhttp://multimedia.mcb.harvard.edu/anim_innerl ife.html

9. Why Carbon BondStrength (kJ/mol) C – C347 – 356 C = C611 C = C837 C – O336 C – H356 – 460 Si – Si230 Si – O368 O – O146 O = O498 N – N163 N = N418 N = N946 What can we learn from this? C – C bond is stronger than C – O –Stable in oxygen rich environment! Two C – C bonds are stronger than one C = C –Chains are stable! C – H bond is strong –Hydrocarbons stable at room temperature!
