Summary
A low molecular weight fraction of a polyphloretin phosphate (PPP) preparation simulated glycerol in a milieu designed for enzymatic assay of glycerol. It is suggested that a component of this PPP mixture is able to act as an alternative substrate for the ATP-glycerol transfer enzyme; it becomes phosphorylated and thus initiates the series of reactions resulting in a increased conversion of NADH to NAD and the observed changes in absorbance.
