| Abstract: | Under physiological conditions, erythrocytes of the horse metabolized 638 +/- 37 (+/-SE) nmoles glucose/ml cells/hr at 37 degrees C compared to 942 +/- 31 for the cat, 1,329 +/- 44 for the dog, and 1,485 +/- 43 for man. On an absolute basis, pentose phosphate metabolism was similar between species, with species differences in erythrocyte glucose tulization attributable to differences in Embden-Meyerhof pathway metabolism. By examining pentose phosphate pathway recycling, it appears that some functional compartmentation exists within erythrocytes. |
