Summary
The intermediates trapped from experiments on the endogenous respiration of yeast cells, in the presence of phenylhydrazine, suggest that a possible way of oxidation of the stored polysaccharide may be the following: polysaccharide→triose phosphates→pyruvate→acetyl→glycolate→glyoxylate→formaldehyde→formyl→H2O+CO2
It has been also observed that the phenylhydrazine, like 2.4-dinitrophenol, stimulates the endogenous consumption of the polysaccharide reserves of yeast.
