THE HYDROLYSIS OF SODIUM POLYPHOSPHATES 5 4 3 The Hydrolysis of Sodium Polyphosphates LEOPOLDO J. ANGHILERI * a n d ESTHER S. MILLER University of Colorado Medical Center, Veterans Administration Hospital, Denver, Colorado, USA (Z. Naturforsdb. 26 b, 543—545 [1971]; received February 19, 1971) The hydrolysis of 32P-sodium polyphosphates (linear and cross-linked) in aqueous solution has been studied. The radiometric determinations indicate that the ortho-phosphate formation is a slow reaction, and that the amount formed by the linear variety is higher than

3 Phosphorus-based polymers: polyphosphate, polyphosphoric acids, phosphonate, and polyphosphazene Abstract: Polyphosphate (poly P) is one of the several molecules on the Earth that effectively store energy within their covalent bonds, Polyphosphate (polyp) is an ester of many structural units of tetrahedral phosphate connected together by high- energy phosphoanhydride bonds. It is found in high abundance in living and non- living things. In this chapter, we discuss about the chemistry of polyphosphates and their applications for the material community in various

Abstract

The polyphosphate component in MP NMR spectra of the Gram-positive Propionibacterium acnes increased after hyperthermia treatment. The cells were exposed to temperatures in the interval from 15 °C to 45 °C. The amount of polyphosphate increased with increasing temperature. There were no temperature induced changes in the other phosphorous components seen in the spectra with exception of a decrease in ATP for higher temperatures. The increase in polyphosphates was less than that obtained from cells irradiated by near ultra-violet light.
