[Variability of biological glucose transport activity in human erythrocytes].
Glucose transport activity was determined on erythrocytes from healthy adult and children. A large variability of values was found between each donor, but transport rate was significantly higher in erythrocytes from adults than those from children. In opposite, the same number of glucose transport sites was found on erythrocytes from adult and children, suggesting that transporters from adult erythrocytes exhibited an higher own activity than transporters from child erythrocytes. Involvement of various factors in glucose transport activity was discussed.
