Polyphosphate - Wikipedia
网页A polyphosphate is a salt or ester of polymeric oxyanions formed from tetrahedral PO 4 (phosphate) structural units linked together by sharing oxygen atoms. Polyphosphates can adopt linear or a cyclic (also called, ring) structures. In biology, the polyphosphate esters ADP and ATP are involved in energy storage.

网页2012年6月6日 · Inorganic polyphosphate (polyP) is structurally very simple, consisting of linear polymers of orthophosphate linked by high-energy phosphoanhydride bonds (Figure 1). At physiologic pH, each internal phosphate unit of polyP carries a monovalent negative charge, making polyP an intensely anionic polymer.
