Molecular species of some glycerophospholipid classes of soft coral \(\textit{Sinularia leptoclados}\) collected in Nha Trang, Khanh Hoa

In the soft coral Sinularia leptoclados, 30 molecular species belonged to 4 glycerophospholipid classes, including 8 ethanolamine (PE), 13 choline (PC), 3 serine (PS) and 6 inositol (PI) were identified. PE 18:1e/20:4, PC 18:0e/20:4, PS 18:0e/24:5 PI 18:0/24:5 are most abundant with value of 69.94%, 45.57%, 68.55% 68.18%, respectively. The PE, PC, classes reported contain alkylacylphospholipid; meanwhile, a considerable level diacylphospholipid is found in PI. A large portion C20:4n polyunsaturated fatty acid was PC; C16, C18, C22, C24 acids at minor level. dominant tetracosapolyenoic C24. presence specific for biosynthesis zooxanthellae18:4n 22:6n, influenced class by lipid composition symbiotic microalgae. 16:0e/18:4 18:1e/22:6 recorded content 1.69% 8.05% evidence transportation from zooxanthellae host corals.
