Phosphoric ACID is a colorless, odorless phosphorus-containing inorganic acid. Phosphoric acid is a sequestering agent which binds many divalent cations, including Fe++, Cu++, Ca++, and Mg++. Phosphoric acid is used in dentistry and orthodontics as an etching solution, to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed. In addition, phosphoric acid is a constituent in bone and teeth, and plays a role in many metabolic processes.
Phosphoric acid, also known as phosphate or [po(OH)3], belongs to the class of inorganic compounds known as non-metal phosphates. These are inorganic non-metallic compounds containing a phosphate as its largest oxoanion. Phosphoric acid has been detected in multiple biofluids, such as feces, urine, and blood. Within the cell, phosphoric acid is primarily located in the cytoplasm. Phosphoric acid exists in all eukaryotes, ranging from yeast to humans. In humans, phosphoric acid is involved in the glutamate metabolism pathway, the glutathione metabolism pathway, the glycerol phosphate shuttle pathway, and the purine metabolism pathway. Phosphoric acid is also involved in several metabolic disorders, some of which include the hypophosphatasia pathway, the leigh syndrome pathway, creatine deficiency, guanidinoacetate methyltransferase deficiency, and L-arginine:glycine amidinotransferase deficiency. Phosphoric acid is a potentially toxic compound.
