Accordingly, (secondary) phosphate is generally only preserved in enclosed spaces, such as a tightly-closed bivalve shell. [ 3 ] Higher concentrations of phosphate in the sea water do not enhance phosphatization, as may seem natural; rather, it increases the rate at which the organism breaks up, perhaps because the mineral "fertilizes" the ...
Gold(III) phosphate is a chemical compound with the formula AuPO 4. It is a pale yellow solid that is insoluble in water and acetone . It decomposes at 450 °C into gold metal, phosphorus pentoxide , and oxygen .
Butylphenyl diphenyl phosphate and propylphenyl diphenyl phosphate became available after 1960. [ 75 ] In addition to their use as hydraulic base-stock, organophosphates (tricresyl phosphate) and metal organothiophosphates ( zinc dithiophosphate ) are used as both an antiwear additives and extreme pressure additives in lubricants , where they ...
The OCP Group (OCP S.A.) (formerly Office Chérifien des Phosphates) is a Moroccan state-owned phosphate rock miner, phosphoric acid manufacturer and fertilizer producer. [2] [3] Founded in 1920, the company has grown to become the world's largest producer of phosphate and phosphate-based products and it is one of the largest phosphate, fertilizer, chemicals, and mineral industrial companies ...
After glycogen phosphorylase catalyzes the phosphorolytic cleavage of a glucosyl residue from the glycogen polymer, the freed glucose has a phosphate group on its 1-carbon. . This glucose 1-phosphate molecule is not itself a useful metabolic intermediate, but phosphoglucomutase catalyzes the conversion of this glucose 1-phosphate to glucose 6-phosphate (see below for the mechanism of this reactio
The systematic name is guanosine-3′,5′-bis(diphosphate) 3′-diphosphohydrolase. Other names in common use include guanosine-3′,5′-bis(diphosphate) 3′-pyrophosphatase, PpGpp-3'-pyrophosphohydrolase, and PpGpp phosphohydrolase. This enzyme participates in purine metabolism.
The anhydrous forms can be prepared by heating dicalcium phosphate: [2] 2 CaHPO 4 → Ca 2 P 2 O 7 + H 2 O At 240-500 °C an amorphous phase is formed, heating to 750 °C forms β-Ca 2 P 2 O 7 , heating to 1140 - 1350 °C forms the α-Ca 2 P 2 O 7 .
The enzyme 3′(2′),5′-bisphosphate nucleotidase (EC 3.1.3.7) catalyzes the reaction adenosine 3′,5′-bisphosphate + H 2 O ⇌ {\displaystyle \rightleftharpoons } AMP + phosphate This enzyme belongs to the family of hydrolases , specifically those acting on phosphoric monoester bonds.
