Major polar lipids are phosphatidylglycerol diphosphatidylglycerol
The results indicated the presence of three major phospholipids including phosphatidylglycerol, diphosphatidylglycerol
, and phosphatidylethanolamine .
) is a unique phospholipid that plays an important role in cell membrane adaptation.
The most dominant phospholipid species in the control PM of [SLM.sub.046] and Okapi were PC, PE, PS and PG whereas those in 150 and 200 mM NaCl PM were PG, PE, PS and diphosphatidylglycerol
Cardiolipin (CL)  is a unique phospholipid with a dimeric structure (diphosphatidylglycerol
) that contains four acyl groups and carries two negative charges.
The following reagents were obtained from Sigma: cardiolipin (diphosphatidylglycerol
), sodium salt from beef heart, 4.8 g/L in ethanol; o-phenylenediamine dihydrochloride (OPD), 30-mg tablets; p-nitrophenyl phosphate, disodium; and diethanolamine, ACS reagent grade.
