The fresh water diatomGomphonemaparvulum (Bacillariophyceae) produces the algalpheromoneshormosirene 2 (C11H16) and dictyopterene A 16 (C11H18) from highly unsaturated eicosanoic acids like 20:5 (ω−3) 21 and 20:4 (ω−6) 14. The oxidative degradation is believed to proceed by cleavage of an intermediate 9-hydroperoxide like 6 by a hydroperoxide-lyase to yield 9-oxo-nona-(5Z.7E)-dienoic acid 8 and
淡水硅藻Gomphonema parvulum(芽孢杆菌科(Bacillariophyceae))由高度不饱和的二十碳酸(如20:5(ω-3)21和20:4 )产生藻类信息素hormosirene 2(C 11 H 16)和双美蝶烯A 16(C 11 H 18)。(ω -6)14。认为氧化降解是通过氢过氧化物裂解酶裂解中间体9-氢过氧化物如6而进行的,从而产生9-氧代壬二-(5 Z .7 E)-二烯二酸8和相应的C 11。烃。通过鉴定和合成新型极性脂肪酸片段8确认了生物合成序列。
