It is current teaching that change in pH results from alteration of the ratio, in circulating plasma, between concentrations of bicarbonate ions ([Hco3]p) and of dissolved CO2 molecules plus carbonic acid.2 This interrelationship is presented in the Henderson-Hassel-balch equation, Where Pco2 is ...
(1950) shows that the 18O16O ratio of rapidly precipitated calcium carbonate depends upon the pH value of the solution and discloses that the oxygen isotope equilibrium fractionation between the sum of the dissolved carbonate species and water is linearly related to the equilibrium between the ...
Bicarbonate anion is considered "labile" since at a proper concentration of hydrogen ion (H+) it may be converted to carbonic acid (H2CO3) and thence to its volatile form, carbon dioxide (CO2) excreted by the lung. Normally a ratio of 1:20 (carbonic acid; bicarbonate) is present in ...

Data analysis was complicated by the need to consider the Donnan ratio of the charged species inside and outside the cells. This work appears to be the first, involving the present NMR procedure, for studying fast membrane transport of a molecule other than water. 展开 ...
Ionic compounds are formed between oppositely charged ions. Positive ions are called cations and negative ions are called anions. The ratio of cations to anions has to be such that the resulting compound is electrically neutral. Answer and Explanation: ...
作用机制 The antacid potential of potassium bicarbonate is attained by increasing the gastrointestinal pH by neutralizing hydrochloric acid. The increase in pH results in suppression of the action of pepsin which is the enzyme that exacerbates ulceration due to the presence of acid. 吸收 Potassium...
This group has a pK′ value ranging from 7.8 to 10.6, with a typical value of about 8. In plasma, the protein buffer system has a limited role; the principal plasma buffer is the bicarbonate–carbonic acid system, and hemoglobin buffers a major portion of the hydrogen ions produced by ...
