Urine pH and carbonic anhydrase activity in the marine dogfish.
EVERAL S years ago it was reported by Smith (I) that the acidity of the urine in both the marine dogfish and sculpin is fixed at about PH 5.7 and cannot be changed by the intravenous administration of sodium bicarbonate, alkaline phosphate or phlorizin. The suggestion was then made that this fixation of urine PH might be related to the fact that in the marine fishes the urine contains large qua...

Logan, R. W., Crooks, S. M., Hutchison, J. H., and Kerr, M. M. (1973). Archives of Disease in Childhood, 48, 256. Blood carbonic anhydrase activity in the newborn. Erythrocyte carbonic anhydrase activity was measured in 7 adults, 12 mature newborn infants, 12 preterm low birthweight infants, 9 'dysmature' infants, 33 infants with the respiratory distress syndrome (RDS), and 5 infants who had re...
متن کاملThe effect of substrate concentration, pH and other factors upon the activity of carbonic anhydrase.
calculating the extra rate in this unit at a series of instants during the course of the manometric experiment. These extra rates are then extrapolated to zero time so as to eliminate changes in the activity of the enzyme during the actual experiment owing to (i) progressive alterations in pH, substrate and buffer concentrations as C02 is taken up or evolved, (ii) destruction brought about byth...
متن کاملInvestigation of solvent effect on the active site energy of Carbonic Anhydrase and Ribonucleotide Reductase
Enzymes catalyze many biological reactions. The rates of chemical reaction in the presence ofenzymes are, in some cases, accelerated more than 10 orders of magnitude relative to thecorresponding rates in solution.In this paper a comparison between optimized structures of two enzyme molecules in aspect ofenergy and dipole moment in different conditions including presence of metallic ion, without...
متن کاملDetermination of carbonic anhydrase (E.C. 4.2.1.1.) activity by means of the pH-stat-technique.
An improved pH-stat-technique for the determination of carbonic anhydrase is presented. As compared with common techniques the main advantages are: 1. The hydration reaction of CO2 catalyzed by carbonic anhydrase can be determined at a constant and selected pH-value, 2. the substrate concentration can be kept constant, 3. the reaction volume amounts to only 2 ml, and 4. the reaction can be meas...
