WebPhosphonates are one of the three sources of phosphate intake in biological cells. [citation needed] The other two are inorganic phosphate and organophosphates.The naturally occurring phosphonate 2-aminoethylphosphonic acid was first identified in 1959 in plants and many animals, where it is localized in membranes. Bisphosphonates are a class of drugs that prevent the loss of bone density, used to treat osteoporosis and similar diseases. They are the most commonly prescribed drugs used to treat osteoporosis. They are called bisphosphonates because they have two phosphonate (PO(OH) 2) groups. They are thus also called diphosphonates (bis- or di- + phosphonate). easwebclient
