“…Nevertheless, in contrast to 22:6(n-3), 22:5(n-3) is found in plankton only in traces (Tinoco 1982). Joseph (1979), working with the medusa Maeotias inexpecta, presumed that 22:5(n-3) [also 22:4(n-6)] can be accumulated in the organism due to the low activity of A4-desaturase (Fig. 1).…”

Fourteen reef-building coral species of Anthozoa and Hydrozoa classes, collected in various regions of the Indo-Pacific, were analyzed for fatty acid composition by gas-liquid chromatography. Total lipids of the corals had the same set of fatty acids. The main fatty acids were 16:0, 18:0, 18:l(n-g), 20:4(n-6), 20:5(n-3) and 22:6(n-3), but some coral families had significant levels of characteristic fatty acids. Poc~lloporidae -20:3(n-6), Acroporidae -18:3(n-6), 18:4(n-3) and 22:4(n-6); Poritidae -18.3(n-61, Milleporidae -22:4(n-6), 22:5(n-6) and 22:6(n-3). Related species of Pocilloporidae from Vietnam and Seychelles differed greatly in their content of saturated a c~d s -50 to 60 D/a and 30 %, respectively. As shown for Stylophora pistillata, the depth of the habitat affects the degree of fatty acid unsaturation and (n-3)/(n-6) ratio of neutral lipids, but does not affect phospholipid fatty acids. A possible role of A5-and A4-desaturases in determining fatty acid pool formation in reefbuilding corals is discussed with reference to their nutritional characteristics.

“…Although less is known about many other taxa of zooplankton, they appear to biosynthesize the relatively more common FA described above (Dalsgaard et al 2003) . Certain benthic bivalve mollusks and carnivorous gastropods produce unusual FA, in which the double bonds are separated by more than one methylene group (i.e., non-methylene interrupted, NMI FA) (Joseph 1982 ;Budge et al 2007) . Fishes, birds, and mammals have the greatest restrictions on FA biosynthesis and follow the typical animal pattern described above.…”

“…In healthy corals, triacylglycerol (TG) and wax esters (WE) are the main storage lipids, accounting for 40 to 73% of total lipids, with sterols (ST) and polar lipids (PL), the main structural lipids, making up 9 to 60% of total lipids (Harland et al 1993, Yamashiro et al 1999, Grottoli et al 2004). The majority of PL (> 80%) is composed of widespread phospholipids (phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine), and less common phosphonolipids (Joseph 1979, Lam et al 1981, Latyshev et al 1986, Imbs et al 2006.…”

The lipid class and fatty acid (FA) composition for 93 species of reef-building and soft corals from the South China Sea (Vietnam) were analyzed and statistically compared to study systematic patterns of the distribution of lipids in corals and the influence of zooxanthellae on the lipids of symbiont-host association. The lipid and FA compositions of hexacorals and octocorals significantly correlated with their taxonomic position, but the lipid features of species within each of these systematic groups mainly depended on the presence of zooxanthellae. The hexacorals had lower content of polar lipids (PL), sterols (ST), and monoalkyldiacylglycerols (MADAG), but higher content of triacylglycerols (TG) and wax esters (WE) than the octocorals. On average, zooxanthellate species contained less structural lipids (PL+ ST), but more MADAG when compared to azooxanthellate species. Tetracosapolyenoic acids 24:5n-6 and 24:6n-3 were chemotaxonomic markers for octocorals, whereas 22:5n-6 was a marker for Milleporidae. A strong correlation was apparent between zooxanthellate coral family and/or genus and the content of the unsaturated FA; 12 FAs were significant for the separation of azooxanthellate and zooxanthellate specimens. The latter had lower concentrations of 7-Me-16:1n-10, 18:1n-7, and six C 20 -24 polyunsaturated FA, but higher concentrations of 16:0, 16:2n-7, 18:3n-6, and 18:4n-3. The presence of > 2% of 18:3n-6 and 18:4n-3 of total FA is characteristic of zooxanthellate corals. An inverse correlation was established between the content of 18:3n-6 and 16:2n-7 in zooxanthellate soft corals. The present study highlights the importance of zooxanthellae in coral lipid metabolism, especially when compared with symbiont-host exchanges in reef-building and soft corals.
