Well, the purpose is to basically destabilize this molecule once we add that phosphoral group that destabilizes our molecule. And now in the next step, we can basically cleave the molecule into two, three carbon molecules. So in the first step, fructose is the sporulated at carbon one. By fructokinase that destabilizes our fructose also traps that fructose in a cell. And now we can basically cleave that fructose by the activity of an enzyme we call fructose one phosphate. Aldolase.
