However, no TBARS (2-thiobarbituric acid reactive substance) formation was detected in a solution containing 2 -deoxyribose (or 2\u2032-deoxyguanosine, etc); where (HPTP) represents N,N,N\u2032-N\u2032-tetrakis(2-pyridylmethyl)-1,3-diamino-2-propanol.

DFT (density-functional theory) calculations on the peroxide adduct of monomeric zinc(II) have supported the above consideration. Similar DFT calculations on the peroxide adducts of the Al(III) and La(III) compounds have revealed that electrophilicity of the peroxide ion in these com\u00ad pounds is strongly reduced.
