Fatty acids of sphingomyelin from amniotic fluid of normal and diabetic pregnancies.

Abstract

Amniotic fluid collected from 14 normal and 11 diabetic patients was analyzed for phospholipids, and separated sphingomyelin and lecithin fractions were further studied for their acid composition by gas liquid chromatography. Notable differences in percent fatty acid composition of sphingomyelin were observed for palmitic (16:0; diabetic less than normal), oleic (18:1; diabetic greater than normal), behenic (22:0; diabetic less than normal) and arachidic acid (20:0; absent in diabetics) in the specimens studied. Notable differences were not observed in fatty acids from lecithin fraction. Fatty acid composition of sphingomyelin from amniotic fluid is similar to fatty acid distribution in sphingomyelin from serum and erythrocyte and suggests maternal origin of the lipid.
