| 2-heptenal | A monounsaturated fatty aldehyde that is (2E)-hept-2-ene which is carrying an oxo group at position 1. Found in the peel of Malaysian pink and white pomelo peel and in the scent gland secretion of the rice stink bug Oebalus pugnax. | (E)-hept-2-enal |
| 2-nonenal, (trans)-isomer | A monounsaturated fatty aldehyde that is (2E)-non-2-ene which is carrying an oxo group at position 1. | (E)-non-2-enal |
| caprylic aldehyde | A saturated fatty aldehyde formally arising from reduction of the carboxy group of caprylic acid (octanoic acid). | octanal |
| decanaldehyde | A saturated fatty aldehyde formally arising from reduction of the carboxy group of capric acid (decanoic acid). | decanal |
| heptanal | An n-alkanal resulting from the oxidation of the alcoholic hydroxy group of heptan-1-ol to the corresponding aldehyde. An endogenous aldehyde coming from membrane lipid oxidation, it is found in the blood of lung cancer patients and has been regarded as a potential biomarker of lung cancer. | heptanal |
| n-hexanal | A saturated fatty aldehyde that is hexane in which one of the terminal methyl group has been mono-oxygenated to form the corresponding aldehyde. | hexanal |
| nonanal | A saturated fatty aldehyde formally arising from reduction of the carboxy group of nonanoic acid. Metabolite observed in cancer metabolism. | nonanal |
| undecanal | A saturated fatty aldehyde formally arising from reduction of the carboxylic acid group of undecanoic acid. It is a component of essential oils from citrus plants like Citrus reticulata. | undecanal |
