Anhydrous iron(III) pyrophosphate can be prepared by heating the mixture of iron(III) metaphosphate and iron(III) phosphate under oxygen with the stoichiometric ratio 1:3. The reactants can be prepared by reacting iron(III) nitrate nonahydrate with phosphoric acid. [5]
Carbon atoms from ribose in PRPP form the linear chain and part of the imidazole ring in histidine. [ 15 ] [ 16 ] [ 17 ] The same is true for the biosynthesis of tryptophan, with the first step being N-alkylation of anthranilic acid catalysed by the enzyme anthranilate phosphoribosyltransferase .
When crystallized from water, it forms a hexahydrate, but it dehydrates above room temperature. Pyrophosphate is a polyvalent anion with a high affinity for polyvalent cations, e.g. Ca 2+. Disodium pyrophosphate is produced by heating sodium dihydrogen phosphate: 2 NaH 2 PO 4 → Na 2 H 2 P 2 O 7 + H 2 O
Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate , sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate .
Chemical phosphorus removal is a wastewater treatment method, where phosphorus is removed using salts of aluminum (e.g. alum or polyaluminum chloride), iron (e.g. ferric chloride), or calcium (e.g. lime). Phosphate forms precipitates with the metal ions and is removed together with the sludge in the separation unit (sedimentation tank ...
Sodium hexametaphosphate is the alkali salt of one of the series of polymetaphosphoric acids (acids formed by the polymerization of phosphate groups). [14] Hexametaphosphoric acid was first made in 1825 by the German chemist Johann Frederich Philipp Engelhart (1797-1853). [15]
Codeine/paracetamol, also called codeine/acetaminophen and co-codamol, is a compound analgesic, comprising codeine phosphate and paracetamol (acetaminophen). Codeine/paracetamol is used for the relief of mild to moderate pain when paracetamol or non-steroidal anti-inflammatory drugs (NSAIDs; such as ibuprofen, aspirin, and naproxen) alone do not sufficiently relieve symptoms.
