8(Z),11(Z),14(Z)-Heptadecatrienal

8(Z),11(Z),14(Z)-Heptadecatrienal is a polyunsaturated fatty aldehyde. It is formed from α-linolenic acid (Item Nos. 90210 | 21910) via a 2(R)-hydroperoxy-9(Z),12(Z),15(Z)-octadecatrienoic acid intermediate.¹ It is also a degradation product of 2(R)-hydroperoxy linolenic acid. 8(Z),11(Z),14(Z)-Heptadecatrienal (100 µM) is active against the plant pathogenic bacteria P. syringae.² It protects Arabidopsis plants against infection by the bacteria Pst DC3000 when injected into the leaves at a concentration of 150 µM prior to bacterial inoculation.³
