Composition of fatty acids of different phospholipids of the intestinal mucosa of the fasting rat during the period of absorption


, : Composition of fatty acids of different phospholipids of the intestinal mucosa of the fasting rat during the period of absorption. Bull Soc Chim Biol 45(1): 137-144

The phospholipids of intestinal mucosa of fasting rats and of rats having received a meal containing 10 p. 100 lard were separated by silicic acid column chromatography and thin layer chromatography. The variations in the levels of the different phospholipids between the fasting state and the absorption period affect mainly the minor constituents (increased levels of inositol kephalins, lysokephalins and sphingomyelins); the levels of choline lecithins and plasmalogens and of serine kephalins decrease, that of phosphatidic acids changes little. In the phosphatides, fatty acids with 12 to 22 C atoms are found. Palmitic and stearic acid are present in the highest proportions. In fasting animals, the main constituents are the most unsaturated phosphatidic acids and the most saturated ethanolamine and serine lecithins, sphingomyelins and kephalins. During the absorption period the saturated acids increase in quantity, mainly in phosphatidic acids, lecithins, plasmalogens and sphingomyelins. Stearic acid is the dominant acid of ethanolamine and serine lecithins, plasmalogens, kephalins in fasting animals; in animals in the re-sorption period, its level rises mainly in the phosphatidic acids. Palmitic acid is the dominant acid of lecithins and sphingomyelins in the mucosa of the fasting rat and its level rises still more in the absorption period.
