The estimation of pyrophosphate in urine with uridine-5'-diphosphoglucose pyrophosphorylase.


PMID 208803

Abstract

The concentration of pyrophosphate in urine has been determined using the enzyme uridine-5'-diphosphoglucose pyrophosphorylase. The technique is relatively quick and easy to perform. Reproducibility of results was good, and results from recovery experiments were excellent. The mean concentration of pyrophosphate found in early morning urine samples from 14 normal adults was identical with that reported by other workers using an ion-exchange method to measure pyrophosphate. The pyrophosphate concentration was related approximately to the phosphate concentration.
