The potential health values of certain mo-inositol phosphates are well known. However, attempts to produce defined isomers of the different partially phosphorylated myo-inositol phosphates by non-enzymatic phytate hydrolysis or chemical synthesis is often associated with high expense and is not very efficient. Enzymatic phytate dephosphorylation was recognized as a cost effective strategy to ma...

The ,8-chain of rhinoceros hemoglobin contains glutamic acid at position ,82, an important site for the binding of organic phosphates. We have investigated the oxygen binding properties of this hemoglobin and its interaction with ATP, 2,3-diphosphoglycerate, CO 2 and chloride. The results show that the presence of GLU at position ,82 nearly abolishes the effect of organic phosphates and CO2, wh...

The recent interest in inositol phosphates as second messengers (e.g. Berridge & Irvine, 1984) has led to many experiments being performed using myo-['H]inositol to label cells, followed by stimulation and subsequent quantification of radiolabelled inositol phosphates (e.g. Berridge et al., 1982, 1983). We have recently become aware of two instances in which considerable loss of radiolabelled i...

Recent studies have considerably clarified the mechanism ofhydrolysis of ribonucleic acids (RNA) by pancreatic ribonuclease and by spleen phosphodiesterase. Digestion ofRNA with ribonuclease results in the splitting of all pyrimidine-pyrimidine internucleotidic links and of those pyrimidine-purine internucleotidic links which involve C(3w) of the pyrimidine nucleotide (Schmidt et al. 1951; Mark...

background: phosphorus is an indispensable element for the growth of animals and plants. there are several environmental problems related to phosphate; therefore, the technical and economic methods of removing phosphate are of great importance. this study evaluated the efficiency of polyaniline/ni0.5zn0.5fe2o4 magnetic nanocomposite in removing phosphate from aqueous environments. methods: the ...

Compounds of Al, Fe, Ca, and Mg phosphates were particularly found in the Lake Okeechobee drainage basin in Florida. Identification of the spectral characteristics of these compounds would improve sensing of phosphorus (P) concentration in soil samples. This study investigated the effects of common soil P compounds on reflectance spectra of sandy soils using ultraviolet (UV), visible (VIS), and...

Cerebral hypoxia-ischemia was produced in 7-day postnatal rats by unilateral carotid artery ligation combined with systemic hypoxia (8% O2). Levels of high energy phosphates, which were only slightly altered in the contralateral hemisphere, were nearly depleted in the ipsilateral hemisphere during the 3-h hypoxic insult. With hypoxia of between 1 and 3 hours' duration, columnar alterations of c...

(REE,Y) phosphates were synthesized in a 1 atm furnace by ß ux-growth methods involving Pb-free ß uxes. Microcrystalline (REE,Y) phosphate was precipitated from a solution of (REE,Y) chlorides or nitrates plus ammonium dihydrogen phosphate, and mixed with a M2CO3 (M = Li or Na)-MoO3 ß ux (75:25:2 molar ratio M2CO3:MoO3:REEPO4). Crystal growth was achieved over the temperature range 1350–870 °C,...
