Abstract

1. 1. Glycerol and glyeerol derivatives transport was compared in human, dog and camel erythrocytes. 2. 2. The camel erythrocytes had the slowest glyeerol transport, that of the dog erythrocytes was also slow, while the quickest transport occurred in human erythrocytes. 3. 3. In glyeerol mono-, di- and triacetates the transport in camel and dog erythrocytes increased until in the triacetate the quickest transport was found. 4. 4. Addition of copper ions had no inhibiting effect on glyeerol transport in camel erythrocytes but a striking effect was seen in human erythrocytes. 5. 5. Changes in pH greatly affected transport in camel erythrocytes, a decline in pH enhanced and an increase in pH slowed the transport. Storage of camel erythrocytes did not affect the glyeerol transport in camel erythrocytes. 6. 6. It is concluded that the mechanism of glyeerol transport in camel erythrocytes is one of a non-facilitated diffusion.
