And so what will happen is a rearrangement will take place. And in this rearrangement, the molecule that is basically kicked off is the first product of this reaction. In this particular case, because we used Zelulose phyphosphate, the product molecule is glyceroldehyde three phosphate. So this is the aldos product that we form in this reaction. So what happens is this Sigma bond is broken as a result of a Pi bond that is formed between this oxygen and this carbon. And so when this Sigma bond is broken, this H ion basically departs.
