✦ Synopsis

Erythrocytes from different cattle were shown to fall into two distinct groups with respect to fructose transport. The rates of entrance of fructose into the two classes of cells differed by a factor of 5 to 10. It was also found that one pathway, the slower, was susceptible to inhibition by glucose while the other was not. The characteristics of the two fructose transport systems remained constant for as long as a week (longest time studied) upon storage at 2°C. The differences observed could not be attributed to handling of the blood, to the relative glucose permeability, or to the age or sex of the animal. This work indicates that two different fructose transport systems are operating in beef erythrocytes of different individuals.
