The relative fraction of major phospholipids in trophoblastic ABs, MVs,
and EXs, including phosphatidylcholine (PC), phosphatidylethanolamine (PE),
phosphatidylserine (PS), phosphatidylinositol (PI), phosphatidylglycerol (PG),
cardiolipin (CL), phosphatidic acid (PA), bis-monoacyl-glycerophosphate (BMP),
lysophosphatidylcholine (LPC), lysophosphatidylethanolamine (LPE) and
sphingomyelin (Sph) species. The lower part of the panel shows the fraction of
the depicted phospholipids, defined by their general properties.
