Comparison of the Lipids in Maternal and Cord Blood and of Human Amniotic Fluid.

Abstract

A paper chromatographic analysis of the lipids in maternal and cord blood and human amniotic fluid indicated that the reduced lipid content of cord blood was confined to the plasma where phosphatidyl ethanolamine and ethanolamine plasmalogen were disproportionately lower. The lipid pattern of amniotic fluid resembled that of red cells and was especially characterized by a large neutral lipid component believed to contain free glyceryl ether.
