【 摘 要 】

Activation energy E _A of the sulfate ions transport process across human erythrocyte membranes modified by reductive methylation has been measured. It has been found that exhaustive reductive methylation (3 times) with formaldehyde and borohydride inhibits the sulfate-equilibrium exchange, by a maximum of about 40%. However, methylation has no measurable effect on activation energy, since the evaluated E _A values for control and methylated cells remain the same within the experimental error range.
