Figure 7. Reaction of 20 mM deoxyribose with Fe(II) and ferrous Haemoglobin (Hb) incubated at 37°C over time periods of up to one hour.

Figure 7

The sugar is degraded on exposure to hydroxyl radicals. The reaction mixure is heated under acidic conditions using TAA to form malondialdehyde (MDA) which reacts with TBA to form a pink chromogen. The absorption was measured at 532 nm after incubation of deoxyribose (▪), with 1.66 µg Fe(II) (•), and with 35 µg Hb (▴).
