These important carbon-based molecules are vital to life in that they provide cells with energy. Carbohydrates are composed of carbon, hydrogen, and oxygen in a set proportion. Where n is any whole number, the formula is: Cn(H2O)n. H— C —OH Carbohydrates are easily soluble in water due...
Peptide nucleic acids (PNA) have been developed to hybridize to single and double stranded nucleic acids. PNA are nucleic acid analogs in which the entire deoxyribose-phosphate backbone has been exchanged with a chemically completely different, but structurally homologous, polyamide (peptide) backbone ...
The method used was adapted from Puntel et al. [20]. The methanolic solution of the extracts was prepared at concentrations from 125 to 2000 µg/mL. For the test, 450 μL potassium phosphate buffer (7.5 mM), 150 μL deoxyribose (1.5 mM), 240 μL H2O2(0.8 mM), 240 μL FeSO4(80...

Once produced, the rCCl3• to rCCl3OO• radicals could reach the DNA and influence the rO2•− that could attack rDNA nucleic bases or deoxyribose residues (Scheme 1), producing damaged bases or strand disruption [29], cellular events that can be quantified by comet assay [58]. Never...
Furthermore, the fragment ion at m/z 125 corresponded to [M+-H-deoxy ribose] of thymine after the loss of the deoxyribose moiety. In addition, the ESI MS/MS spectrum of compound 4 in positive mode (Figure S11) showed a protonated molecular ion peak at m/z 245 [M+H]+ and daughter...
Other utilized assays that demonstrated the strong antioxidant activity of anthocyanins and anthocyanidins are ferric reducing/antioxidant power (FRAP), deoxyribose assay (OH• radical scavenging) and NBT superoxide anion scavenging (O2−•) [17,21,22,23,24,25,26,27,28]. In all these assays...
