Methanebisphosphonic acid - Reference Information
| Biological activity | Medronic acid (Methylenediphosphonic acid) is a methylene-substituted bisphosphonate. Medronic acid has an affinity for and adheres to the surface of hydroxyapatite crystals in the bone matrix. Medronic acid accumulates at sites of osteoid mineralization and can be used in combination with radioisotopes in bone imaging. |
