Ratios between chemical bonds related to the lipid peroxidation observed with the FTIR spectra data. Those ratios were as follows: (a) the ratio assigned to 1740 cm−1/2960 cm−1 is related to lipid oxidation, (b) the ratio assigned to 2920 cm−1/2960 cm−1 is related to lipid saturation, (c) the ratio assigned to 3012 cm−1/2960 cm−1 is related to lipid desaturation, and (d) the ratio assigned 1630 cm−1/1650 cm−1 is related to protein aggregation. The dotted line indicates the mean value of the control cells for each ratio; all ratios were compared to the control ratio in each case. PP: polyphenol.
