But the number of different kinds of chemical reaction is surprisingly small. In fact, we saw the same underlying pattern in our discussion of genetic regulation. While the specific details of the vast array of regulatory events may be complicated, only a fairly small number of different principles are needed to explain the essential mechanisms at work in an organism. There is often a surprising degree of simplicity underlying the seemingly complex events of life. As we will see in this chapter, the genetic control of metabolism is no different. But we can never lose sight of the fact that it is the understanding of the specific processes, in all their complexity, that actually makes the difference for an individual patient.
