Graduate Biochemistry 7.51: The Major Concepts As you will see from the syllabus, the lectures in this course are drawn from a wide range of topics in biochemistry. However, nearly all of the science we discuss is based on a discrete number of fundamental concepts that are common to most biochemical approaches. A major goal of this course is to help you to master those concepts, and enable you to use them to approach both classical and novel biological problems. Below, we have listed the recurring elements we consider to be most important. 1) Analyzing reactions: a) The properties of reactions i) Thermodynamics: the relationships among free energy and equilibrium constant, entropy and enthalpy ii) The driving force for unimolecular interactions iii) The order of a reaction, and the relationship between the written statement of a reaction and its order iv) Rate versus rate constant b) Tests of reaction mechanism i) Structural versus kinetic approaches ii) Analyzing intermediates: populated
