As phosphate derivatives form such important intermediates between the functioning of tissues and the metabolism which supports function, we decided to investigate the levels of certain phosphates in brain slices before and during metabolism in vitro. Investigation of this type appeared all the more necessary because there is now an extremely interesting group of observations on the levels of p...

Pirie, van Heyningen & Flanders (1955) showed that the concentrations of certain acid-soluble phosphates in the lens, when estimated by the enzymic method of Slater (1953), were much lower than the concentrations reported by Nordmann & Mandel (1952), who used the barium-fractionation method of LePage (1948, 1949). This method has, until recently, been the accepted and standard one for estimatio...

conclusions in critically ill patients, the symptoms of hypophosphatemia may not be apparent, but clinicians should be vigilant about this complication during therapy. in cases of severe symptoms (e.g., cardiopulmonary distress, anemia and thrombocytopenia, or rhabdomyolysis), phosphate therapy under close surveillance is warranted. introduction although asymptomatic hypophosphatemia is a commo...

Step 2 Phosphating The metal is treated with phosphoric acid, leading to the following two reactions occuring in the zinc-rich surface of the steel: 2H3PO4 + 3Zn → 3H2 + Zn3(PO4)2 2H3PO4 + Fe + 2Zn → 3H2 + FeZn2(PO4)2 This gives a mixture of zinc phosphates. The electrocoat paint binds better to these zinc phosphates than to the steel alone, and the zinc phosphates corrode much slower than the ...

Plastids are the site of the reductive and the oxidative pentose phosphate pathways, which both generate pentose phosphates as intermediates. A plastidic transporter from Arabidopsis has been identified that is able to transport, in exchange with inorganic phosphate or triose phosphates, xylulose 5-phosphate (Xul-5-P) and, to a lesser extent, also ribulose 5-phosphate, but does not accept ribos...

The recognition in the early 1960s by Morifusa Eto that tri-o-cresyl phosphate (TOCP) is hydroxylated by the cytochrome P450 system to an intermediate that spontaneously cyclizes to a neurotoxic phosphate (saligenin phosphate ester) ignited the interest in this group of compounds. Only the ortho isomer can cyclize and clinically cause Organo Phosphate Induced Delayed Neurotoxicity (OPIDN); the ...

Measurement of polymerization degree of condensed phosphates was examined by solid-state NMR. Broad peaks of the NMR of endand middle-PO4 groups of condensed phosphates were observed at about 1 and -20 ppm, respectively. The NMR. peak area ratio (Ro) of middle-PO4 group to end-PO4 group has the following relation with the polymerization degree (n) of polyphosphate: Ro (middle-PO4/end-PO4) = (n-...
