The principal aim of this investigation is to study free radical scavenger capacity of oxidized derivatives of lycopene (LYC) that were reported before as bioactive derivatives/metabolites. The electron transfer mechanism is analyzed in terms of its ionization energies and electron affinities. Lambda maximum (lambda(max)) values are also included. Electron affinity increases and ionization energy decreases as the number of carbon atoms in the backbone and the number of conjugated double bonds augment. The presence of OH improves the electron donor capacity, whereas the presence of the aldehyde group raises the electron acceptor capacity. Di-aldehyde derivatives appear as the best electron acceptors among the molecules investigated. The increased power to accept electrons on the part of the oxidized derivatives may influence anti-cancer properties. Here we report the electronic differences between these molecules. This information will aid in the understanding of different possible mechanisms that may be involved in the prevention of some illnesses like cancer, as reports exist indicating that some of these metabolites can be formed in vivo and are biologically active.
