We have the oxidative and the nonoxidative phase. Now previously we focused on the oxidative phase and we saw that in the oxidative phase, the cells of our body transform a single glucose phosphate molecule into two NADPH molecules and one ribose five phosphate sugar molecule. Now what do our our cells use these two different molecules for? So as we discussed previously, the NADPH molecules are very important reducing agents that exist inside our cells because the cells actually use these molecules to help generate many other biological molecules. So things like fatty acid molecules, cholesterol molecules, nucleotide molecules, neurotransmitters, all these things require NADPH molecules. In addition, the cells also use the NADPH molecules to help detoxify many different types of toxic agents that exist inside our cells.
