Stochiometric Metrics

Can someone support in this ,

I need to express the below reaction that took place in the anaerobic-aerobic batch tests in a stoichiometric matrix.

Anaerobic processes (expressed in COD and phosphorus units, correspondingly):

 Acetate uptake:

1g HAc + 0.43g PP + 0.50 g Glycogen => 1.50 gPHA + 0.43g PO4
