[Effect of vitamin A on lipid metabolism in the erythrocyte membrane]

Metabolism of erythrocyte membrane phospholipids was studied under conditions of distinct A-avitaminosis. Content of sphingomyelin, phosphatidyl serine, phosphatidyl ethanolamine was markedly decreased and of phosphatidyl choline--increased. Content of the phospholipids correlated with incorporation of 2-14C-acetic acid. The rate of Na2H32PO4 incorporation into the phospholipid fractions studied was increased.
