Abstract: The present invention relates to a series of molecules derived from 2,3-diaminopropionic acid (DAP), comprising or not comprising an 8-hydroxyquinoline (8-HQ) motif, and to the use of said molecules for trapping an alpha-oxoaldehyde resulting particularly from the degradation of the glucose or for trapping an alpha-beta-unsaturated aldehyde, resulting particularly from the oxidative degradation of fatty acids. These molecules can have a further application in the fields of cosmetics, food processing, and pharmaceuticals.
