The biosynthesis of cyclopentenyl fatty acids from (2-cyclopentenyl)carboxylic acid (aleprolic acid) via chain-lengthening by C2-units was tested in seeds and leaves of Caloncoba echinata and Hydnocarpus anthelminthica of Flacourtiaceae and in various prepatations of higher plants other than Fla courtiaceae. Only tissues of Flacourtiaceae, where cyclopentenyl fatty acids are found naturally, were able to accept aleprolic acid as a starter molecule for the synthesis of cyclic fatty acids. Labelling patterns of straight chain and cyclic fatty acids, synthesized after incubation of Flacourtiaceae seeds with [1-(14)C[-acetate, indicated de novo synthesis of C16 fatty acids in either case, followed by elongation to higher homologs.
通过C2单位的链延长作用，从（2 - 环戊烯基）羧酸（阿列普罗酸）生物合成环戊烯基脂肪酸，这一过程在大风子科的刺萼大风子和驱蛔大风子的种子及叶片中，以及在大风子科以外的各种高等植物制剂中进行了测试。只有在自然存在环戊烯基脂肪酸的大风子科组织中，能够接受阿列普罗酸作为合成环状脂肪酸的起始分子。用[1 - （14）C] - 乙酸盐孵育大风子科种子后合成的直链和环状脂肪酸的标记模式表明，在这两种情况下均从头合成了C16脂肪酸，随后延长为更高的同系物。
