Fatty acids (FAs) of soft corals contain two very-long-chain tetracosapolyenoic acids (TPA, 24:5n-6 and 24:6n-3),
which are chemotaxonomic markers of all species of the subclass Octocorallia. The distribution of TPA in molecular
species of different phospholipid (PL) classes was investigated for the first time in the soft corals Sinularia macropodia
and Capnella sp. From shallow waters of Vietnam. Phosphatidylethanolamine (PE), phosphatidylcholine (PC),
phosphatidylserine (PS), and phosphatidylinositol (PI) were the major PL classes of S. macropodia and Capnella sp.
More than thirty two molecular species of these four PL classes were determined by high resolution tandem mass
spectrometry. 18:1e/20:4 PE, 18:0e/20:4 PC, 18:0e/24:5 PS, and 18:0/24:5 PI were the major molecular species of
PL in both co.. View More»
