Glucose. The first example of a soluble dehydrogenase 

 is an exception to the generalization just stated: phosphate 

 does not participate in glucose oxidation to gluconate, 

 though pyridine nucleotide (TPN) does. The soluble de- 

 hydrogenase catalyzing this oxidation is a separate enzyme 

 from the particulate enzyme already discussed, since it has
