Sustainability: Inorganic and/or Organic Phosphate?Hendrix, J. L
The quantitative determination of functional P groups, including inorganic orthophosphate, orthophosphate monoesters, orthophosphate diesters, phosphonates, and condensed inorganic and organic phosphates, is well established (Cade-Menun and Preston 1996; Turner et al. Mineralisation of soil orthophosphate mono...
The acid destroys the organic material while the calcium ion prevents loss of phosphate or its conversion to an unmeasurable form. Inorganic phosphate can be determined in the presence of labile organic phosphates since phosphate liberated after the color reaction has been initiated cannot interfere ...
Two different forms of phosphorus are found in municipal sewage: organic andinorganic phosphates. It is present in solution as well as particulate forms. Assimilation of phosphorus by plant or microorganism is the biotic removal mechanism, whereas adsorption of the same by gravel bed is abiotic remo...
The safe maximum concentration of organic and inorganic calcium and phosphate were proposed individually for each composition of parenteral nutrition solutions. Surprisingly, organic calcium with organic phosphate showed precipitation but over the therapeutic range. The protective effect of amino acid was ...
Organic–inorganic hybrid chromium oxophenylphosphate CPP-1 has been synthesized hydrothermally in the presence of phenylphosphonic acid as a phosphorus source without the aid of any structure directing agent (SDA). The material has high BET specific surface area of 315 m2 g−1 and consists ...
Phosphorus is also found in the mineralizing protist world, first as inorganic phosphate anions incorporated into the calcite without disrupting the structure27, similarly to Mg2+in some calcified-biomineralized systems28and secondly as element of the organic mineral-associated molecules like phosphorylated...
Calcium andinorganic phosphateare the two main constituents ofhydroxyapatite, the bone mineral that gives mechanical resistance to the organic matrix. The Ca/P mass ratio in bone is 2.2, and the initial step of Ca–P crystal nucleation takes place within matrix vesicles that appear from the plasm...

Oxygen isotope signature of Pi regeneration from organic compounds by phosphomonoesterases and photooxidation Phosphomonoesters are an important source of dissolved inorganic orthophosphate (PO 4 or P i), the preferred form of P utilized by microbiota and aquatic p... Y Liang,RE Blake - 《Geochimi...
