What is The Fatty Acid and Sterol Composition of Two Marine Dinoflagellates about?

The fatty acid, sterol and chlorophyll pigment compositions of the marine dinoflagellates Gymnodinium wilczeki and Prorocentrum cordarum are reported. The fatty acids of both algae show a typical dinoflagellate distribution pattern with a predominance of Cis, Czo and Czz unsaturated components. The acid 18: 5~3 is present at high concentration in these two dinotlagellates. G. wilczeki contains a high proportion (93.4 %) of 4-methyl-Sa-stanols including 4,23,24-trimethyl-Sa-cholest-22E-en-3fl-ol (dinosterol), dinostanol and 4,23,24-trimethyMa-cholest-7-en-3/3-01 reported for the first time in dinotlagellates. The role of this sterol in the biosynthesis of Sa-stanols in dinoflagellates is discussed. P. cordatum contains high concentrations of a number of A 24'2s'-sterols with dinosterol, 24\_methylcholesta-5,24(28)-dien-3/I-01, 23,24&methylcholesta-5,22E\_dien-3fl-01, 4,24-dimethyl-5acholest-24(28)-en-3~-ol and a sterol identified as either 4,23,24-trimethyl-or 4-methyl-~4-ethyl-5a-cholest-24(28)-en-3/l-ol present as the five major components. The role of marine dinoflagellates in the input of both Cmethyl-and 4-desmethyl-5a-stanols to marine sediments is discussed.
