  • Induction of a wide range of C(2-12) aldehydes and C(7-12) acyloins in the kidney of Wistar rats after treatment with a renal carcinogen, ferric nitrilotriacetate.: Toyokuni et al. explore the biochemical impact of ferric nitrilotriacetate, a renal carcinogen, on the generation of various aldehydes including trans-2,cis-6-Nonadienal in the kidneys of Wistar rats. This research highlights the role of oxidative stress and lipid peroxidation in renal carcinogenesis (Toyokuni et al., 1997).

General description

trans-2,cis-6-Nonadienal is the key contributor to the cucumber flavor. It is also found in mango, ripened anchovy and kelp.
