Abstract
It was shown that TPD passed to the erythrocyte by the similar mechanism as the absorption through the intestinal wall. Our experiments in which TPD and TPD-^<35>S were added to the suspension of the erythrocyte of rabbits showed that TPD immediately passed to the erythrocyte and continued the passage if there was not a chance of being reduced to thiamine in the suspension. The transfer of TPD into the erythrocyte had nothing to do with its esterification, nor replacement of the thiamine, already existed in it. TPD was reduced in the erythrocyte to thamine, releasing propylsulfide.
