Historical Background

Phosphorus is one of the six essential elements for life. Molecules containing anionic phosphate (PO43−) are constituents of genetic material (DNA, RNA) and are an essential building block of phospholipid membranes, bones, and teeth; high-energy phosphate bonds drive cell energetics via ATP/ADP hydrolysis; phosphorylation/dephosphorylation reactions are key events in intracellular signaling, and phosphate acts as an intra- and extracellular pH buffer. In mammals, phosphate is obtained from the diet in the form of inorganic phosphate (Pi) that exists in solution as negatively charged mono- (H2PO4−) and divalent (HPO42−) ions in the physiological pH range. As such Pimust be actively transported “uphill” across the cell membrane from the external medium against...
