Figure 3
The graph colours are related to the magnitude of absorption, with blue being the lowest and red being the highest. (a) EG/SS. (i) Peak at 400 nm corresponding to disulfide radical anion. (ii) Aerial view showing single peak present at 400 nm. (iii) Decay plot with time of the 400 nm peak. (b) EG/SH. (i) No peak present at 400 nm. (ii) Aerial view showing featureless spectra. (iii) No decay plot produced. (c) EG/oxidized α-lipoic acid. (i) Produces 400 nm peak and small peak around 330 nm. (ii) Both peaks are visible in spectrum. (iii) Decay plot. (d) EG/reduced DTT. (i) Reduced DTT did not produce a peak at 400 nm but has small peak at 600 nm. (ii) 600 nm peak visible. (iii) Decay plot.
