Productivity in P limited peatlands is regulated in part by the turnover of organic phosphates, which is influenced by the chemical nature of the compounds involved. We used solution 31P nuclear magnetic resonance (NMR) spectroscopy to quantify organic and inorganic phosphates in benthic floc (a mixture of plant detritus and algae) and underlying soil from sites along P gradients in hard water ...
In addition to salt (NaCl), sodium phosphate also increases the sodium content of meat products. Thus, the effects of replacing sodium phosphate with potassium phosphate on sodium content and properties of low-salt cooked bologna-type sausage and cooked ham were studied. Four sausage formulations were prepared. In formulations 1 and 2, the target sodium content was 0.55 g Na/100 g, and in recip...
In contrast to other vertebrate hemoglobins (Hbs) whose high intrinsic O2 affinities are reduced by red cell allosteric effectors (mainly protons, CO2, organic phosphates, and chloride ions), crocodilian Hbs exhibit low sensitivity to organic phosphates and high sensitivity to bicarbonate (HCO3(-)), which is believed to augment Hb-O2 unloading during diving and postprandial alkaline tides when ...
A large proportion of the organic P in soils can occur as scylloinositol phosphates. These compounds are rarely detected elsewhere in nature and remain poorly understood, partly because conventional procedures for their determination are lengthy and erroneous. We report a straightforward procedure for the determination of scylloinositol phosphates in soil extracts using solution 31P nuclear mag...
The sunlight has an important role in metabolism of calcium ( Ca) and phosphorus ( P). The sunlight has different effects in different places. Therefore the pattern of metabolic disease depends upon geographical place. In this investigation two groups of workers( one group working in shadow and the other under the sunshine) were chosen as control and experimental groups respectively.these two ...
DNA from Ehrlich ascites tumor (EAT) cells and from human placenta was examined for covalent bonds between hydroxy amino acid residues in peptides and nucleotide phosphate groups. The residual proteinaceous material in highly purified DNA was radiolabelled with 125Iodine and the linking-groups between peptides and nucleotides released by combined protease and nuclease treatment were investigate...
Stable Zn isotopes are fractionated in roots and leaves of plants. Analyses demonstrate that the heavy Zn isotopes are enriched in the root system of plants with respect to shoots and leaves as well as the host soil, but the fractionation mechanisms remain unclear. Here we show that the origin of this isotope fractionation is due to a chemical isotope effect upon complexation by Zn malates and ...
The usual method employed in determining the acidity of milk is to add a few drops of a solution of phenolphthalein as indicator to 100 cc. of milk and then titrate with 6 NaOH. By the use of this method it is found that 100 cc. of milk, when strictly fresh, will require the addition of 15 to 20 cc. of the alkali in order to produce a faint but permanent pink coloration. The acidity of fresh mi...
Biomineralization of Uranium-Phosphates Fueled by Microbial Degradation of Isosaccharinic Acid (ISA)
Geological disposal is the globally preferred long-term solution for higher activity radioactive wastes (HAW) including intermediate level waste (ILW). In a cementitious system, cellulosic items present in ILW may undergo alkaline hydrolysis, producing significant quantities of isosaccharinic acid (ISA), chelating agent radionuclides. Although microbial degradation ISA has been demonstrated, it...
