Asymmetry of the hexose transfer system in human erythrocytes. Comparison of the effects of cytochalasin B, phloretin and maltose as competitive inhibitors.
1. Cytochalasin B inhibits glucose transfer in human red cells. With glucose exit the inhibition is typically non‐competitive, but hexose exchange is competitively inhibited. 2. At 16 degrees C theExpand

The asymmetry of the facilitated transfer system for hexoses in human red cells and the simple kinetics of a two component model
1. 4, 6‐O‐Ethylidene‐α‐ D‐glucopyranose (ethylidene glucose) has been used to study the competitive inhibition of glucose exchange fluxes when the reagent was (i) inside the cells and (ii) on theExpand

The Asymmetry of the Hexose Transfer System in the Human Red Cell Membrane
Publisher Summary One of the complexities of the system in the human erythrocyte is that of asymmetry. This chapter reviews some of the several ways in which the hexose transfer system has presentedExpand

Asymmetry of the hexose transfer system in human erythrocytes. Experiments with non‐transportable inhibitors.
1. The asymmetrical nature of sugar affinity for the hexose transfer system in human red cells has been demonstrated using purified 4,6‐O‐ethylidene‐alpha‐D‐glucopyranose (ethylidene glucose) toExpand

Gestational variations in the composition of the foetal fluids and foetal urine in the sheep
Early investigations into the composition of the foetal fluids have been reviewed by Needham (1931). More recently other workers, notably Malan, Malan & Curson (1937), Cloete (1939) and McDougallExpand
