Binding of zinc and calcium to inositol phosphates (phytate) in vitro

Phytate (Inositol Hexakisphosphate) in Soil and Phosphate Acquisition from Inositol Phosphates by Higher Plants. A Review

Phosphate (P) fixation to the soil solid phase is considered to be important for P availability and is often attributed to the strong binding of orthophosphate anion species. However, the fixation and subsequent immobilization of inositolhexa and pentaphosphate isomers (phytate) in soil is often much stronger than that of the orthosphate anion species. The result is that phytate is a main organ...

Inositol phosphates in plants and the development of low phytate crops

Competition of zinc, cadmium and calcium for binding sites in sperm of trout and carp

Heavy metal pollutions of aquatic ecosystems have already raised many concerns on aquaticorganisms’health and survival especially on their sperm. The effects of a single metal on sperm may be totallydifferent from cocktail of several metals because of their interactions, so the effects of zinc, cadmium andcalcium on the trout and carp sperms and their competition have been examined by incubatio...

Inositol phosphates from barley low-phytate grain mutants analysed by metal-dye detection HPLC and NMR.

Inositol phosphates from barley low-phytate grain mutants and their parent variety were analysed by metal-dye detection HPLC and NMR. Compound assignment was carried out by comparison of retention times using a chemical hydrolysate of phytate [Ins(1,2,3,4,5,6)P(6)] as a reference. Co-inciding retention times indicated the presence of phytate, D/L-Ins(1,2,3,4,5)P(5), Ins(1,2,3,4,6)P(5), D/L-(1,2...

Inositol phosphates in aquatic systems

While there is a considerable body of research on the abundance and behavior of inositol hexakisphosphate in soils, much less is known regarding its behaviour in aquatic systems. The observed physico-chemical behaviour of this organic P species suggests that in marine and freshwaters, it should be complexed and precipitated by major ions such as calcium, magnesium, iron or aluminium, and thus i...
