Table 2.
Membrane phospholipid composition of blood components—RBC (Owen et al., 1981), platelets (Owen et al., 1981) and PBMC (Kuliszkiewicz-Janus et al., 2005)—and endothelial cells—BCEC (Tewes and Galla, 2001) and HUVEC (Cansell et al., 1997).
| Phospholipid | Blood components | Endothelial cells | |||
|---|---|---|---|---|---|
| RBC | Platelets | PBMC | BCEC | HUVEC | |
| Phosphatidylcholine (PC) | 30.3 | 40.6 | 43.4 | 37.1 | 53.9 |
| Sphingomyelin (SM) | 27.3 | 19.3 | 16.9 | 17.3 | 22.5 |
| Phosphatidylserine (PS) | 13.4 | 9.3 | 11.0 | 8.8 | 3.0 |
| Phosphatidylinositol (PI) | 0.5 | 2.7 | 28.7 | 7.1 | 6.8 |
| Phosphatidylethanolamine (PE) | 28.4 | 27.9 | 29.5 | 13.7 | |
Values shown in percentage, taking into consideration that the sum of PC, SM, PS, PI, and PE proportions represents 100%.
