The deoxyribose method observes the decrease in build-up of TBARS resulting from degradation of deoxyribose sugar by the hydroxyl radicals promoted by the Fenton reaction (HALLIWELL et al., 1987).
The OH radical scavenging activity was carried out by measuring the competition between deoxyribose and the various extracts from leaves of P.
The reaction containing different concentrations of the extract was incubated with deoxyribose (10mmol/1), [H.sub.2][O.sub.2] (10mmol/1), Fe[Cl.sub.3] (5 mmol/1), EDTA (1 mmol/1) and ascorbic acid (5 mmol/1) in potassium phosphate buffer (50 mmol/1, pH 7.4) for 60 min at 37[degrees]C [13].
RNA is identical to DNA in all but two respects: (1) ribose replaces deoxyribose in the sugar phosphate subunit of each RNA nucleotide; and (2) thymine is replaced by uracil (U), which, however, also binds (i.e., is complementary) to adenine.
The deoxyribose method described by Aruoma and Halliwell [26] was used to determine the hydroxyl radicals trapping capacity of MPE, as per standard method.
Briefly OH* was generated in a non-enzymic system comprised of deoxyribose (2.8 mM), FeSO4*7H20 (2 mM), sodium ascorbate (2.0 mM) and H202 (2.8 mM) in 50 mM KH2PO4 buffer, pH 7.4 to a final volume of 2.5 ml.
Indeed, ONO[O.sup.-] may be an important mediator of free radical-dependent toxicity because of its strong oxidizing properties toward proteins, nonprotein thiols, deoxyribose, and membrane phospholipids.
deoxyribonucleic acid (DNA): Double-stranded nucleic acid composed of adenine, guanine, cytosine, and thymine, in addition to phosphate and deoxyribose.
The crystal structure of the human DNA repair endonuclease HAP1 suggests the recognition of extra-helical deoxyribose at DNA abasic sites.
Hydroxyl radicals were produced in this study by incubating Fe2+/EDTA/H2O2 system with ascorbic acid at pH 7.4 (Fenton reaction) the hydroxyl radical attacks deoxyribose which eventually results in the formation of thiobarbituric acid reacting substances (TBARS).

Hydroxyl radical scavenging was carried out by measuring the competition between deoxyribose and the essential oil and its major constituents ([beta]-pinene, [beta]-caryophyllene and germacrene D) for hydroxyl radicals generated in Fenton reaction.
Methanol extracts of Rhus coriaria fruits inhibited the degradation of deoxyribose mediated by hydroxyl radical produced from the Fe+3/ascorbate/EDTA/H2O2 system.
Previously unknown genes and modifying deoxyribose nucleic acid (DNA) sequences were discovered.
Mitomycin C-induced deoxyribose degradation inhibited by superoxide dismutase.
