WebMar 3, 2024 · Carbonyl stress is a condition characterized by an increase in the steady-state levels of reactive carbonyl species (RCS) that leads to accumulation of their irreversible covalent adducts with biological molecules. RCS are generated by the oxidative cleavage and cellular metabolism of lipids and sugars. α,β-Unsaturated carbonyl compounds can be subclassified according to the nature of the carbonyl and alkene groups. • Parent α,β-Unsaturated Carbonyls • Methyl vinyl ketone, the simplest α,β-unsaturated ketone
