ChEBI: A dialdehyde that is propane substituted by two oxo groups at the terminal carbon atoms respectively. A biomarker of oxidative damage to lipids caused by smoking. It exists in vivo mainly in the enol form. | [Uses]
Propanedial, exists in horseradish hairy root taht has shown strong antioxidant capacity under arsenic stress which indicates possible use of Armoracia rusticana plants for phytoremediation. | [storage]
Unstable and easily polymerizes. The generation of MDA in situ from the hydrolysis of its bis-acetals results in the formation of a number of side products, including β- alkoxyacrolein, 3,3-dialkoxypropionaldehyde, and fluorescent condensation polymers of MDA. Crystalline sodium MDA, which is much more stable than MDA, is the recommended synthetic reagent. Sodium MDA, if stored under nitrogen in a refrigerator, is stable for months. |
