WebApr 14, 2024 · Phytates are a type of organophosphorus compound produced in terrestrial ecosystems by plants. In plant feeds, phytic acid and its salt form, phytate, account for 60%–80% of total phosphorus. Because phytate is a polyanionic molecule, it can chelate positively charged cations such as calcium, iron, and zinc. Due to its prevalence in … Webprocesses that determine the bioavailability of inorganic P Speciation of P-P species The speciation of P, i.e., the distribution of P among various species in solution is first of all determined by solution pH. Indeed, phosphate ions are derived from the dissociation of orthophosphoric acid which is char-acterized by three p K values (Fig. 1).
WebTo find out the distribution and bioavailability of nitrogen (N) and phosphorus (P) species in the urban dusts of Hefei City, 52 samples were collected from impervious areas with six different urban land-use types. WebNumerous studies of fresh-water systems have shown the inseparable link between the chemical form or species of P entering lakes and the potential for P-induced eutrophication (16). Indeed, bioassay measurements indicated that P present as apatites is much less bioavailable to planktonic algae than dissolved phosphate (16).
