separation and capture of carbon dioxide from the flue gas of power plants in order to reduceenvironmental damages has always been of interest to researchers. in this study, aqueous solution ofmethylamine was used as an absorbent for co2 capture. in order to study this reaction, densityfunctional theory (dft) was employed at the level of b3lyp/6-311++g(d,p) by using theconductor-like polarizabl...

Rat liver microsomal glucose 6-phosphate phosphohydrolase has been shown to possess two further catalytic activities: the hydrolysis of inorganic pyrophosphate to orthophosphate and a pyrophosphate-glucose phosphotransferase activity. Physiological concentrations of bicarbonate ion (10 to 50 mM) have been found to inhibit all three activities. A detailed kinetic analysis of the nature and exten...

In this paper, we used quantum chemical approach to shed light on the catalytic mechanism of γ-carbonic anhydrase (γ-CA) to convert carbon dioxide to bicarbonate ion. Density functional theory (DFT) using B3LYP and UB3LYP functional and three split-valance including 6-31G*, 6-311G** and 6-311++G** basis sets were used to calculate the details of electronic structure and electronic energy of act...

Decreases in plasma bicarbonate are associated with hyperchloremic acidosis and lactic acidosis. According to the Stewart approach to acid-base physiology, the strong-ion difference regulates plasma bicarbonate, with chloride and lactate being the only strong anions routinely measured in clinical chemistry. We hypothesized that the plasma strong-ion difference, both with and without lactate, wo...

The pituitary hormone prolactin is a pleiotropic endocrine factor that plays a major role in the regulation of ion balance in fish, with demonstrated actions mainly in the gills and kidney. The role of prolactin in intestinal ion transport remains little studied. In marine fish, which have high drinking rates, epithelial bicarbonate secretion in the intestine produces luminal carbonate aggregat...
