[Comparative study of the fatty acid makeup of the neuronal and glial cell phospholipids in the brain of reptiles, birds and mammals].

Studies have been made on fatty acid composition of phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, phosphatidylinositol and sphingomyelin from the neurons and glial cells of the brain of rats, pigeons (Columba livia) and tortoises (Testudo horsfieldi). It was shown that fatty acid composition of the phospholipids investigated in both cellular fractions of tortoises differs from that of rats and pigeons. Within the same animal, fatty acid composition of homologous phospholipids from the neurons and glial cells is not identical. Differences in this respect were found in all the animals studied, although they are more evident in cells of pigeons and rats than in the cells of tortoises.
