| 3-PENTEN-2-ONE Usage And Synthesis |
Chemical Properties | 3-Penten-2-one has a fruity odor becoming pungent on storage. | Chemical Properties | colourless liquid with a pungent odour | Occurrence | Reported found among the volatile components of roasted peanuts; also in cranberry, mango, bilberry, rum,
cocoa, coffee, tea, roasted filberts, roasted peanuts, potato chips, lingonberry, strawberry fruit and jam, tomato, wheat bread, parmesan
cheese, yogurt, fatty fish, passion fruit, beans, mango, tamarind, rice, Bourbon vanilla, endive, shrimp, katsubushi and buckwheat. | Uses | 3-Penten-2-one was used in the synthesis of the alkaloids (+/-)-senepodine G and (+/-)-cermizine C. | Preparation | From 4-hydroxy-pentan-2-one refluxed with oxalic acid. | Definition | ChEBI: An enone that is pent-2-ene in which the two methylene hydrogens have been replaced by an oxo group. | Taste threshold values | Taste characteristics at 10 ppm: musty, stale water and phenolic with a fishy and shellfish nuance. | General Description | 3-Penten-2-one is volatile compound present in berry fruit of two Aronia melanocarpa genotypes. Urinary 3-penten-2-one is a useful biomarker for increased accumulation of acetaldehyde during abnormal metabolic stress. | Biochem/physiol Actions | 3-Penten-2-one inhibits nitric oxide production and inducible nitric oxide synthase expression via heme oxygenase-1 expression in lipopolysaccharide-activated RAW264.7 macrophages. |
