Figure 4: Second derivative Fourier transform infrared spectra of A549 cancer and clone cells. Mean ± standard deviation values of three experiments were represented for A549 cancer (square) and clones (circle) cells. Wave numbers specific for; (a) A-DNA conformations/DNA-RNA hybrids at 970 and 1245 cm−1, (b) Z-DNA conformation at 1044 and 1067 cm−1, (c) C-O bond of carbohydrate at 1025 cm−1, (d and e) imidazole-metal interactions at 1088 and 1560 cm−1, (f) secondary structure of proteins at 1640, 1654, 1679 and 1696 cm−1, (g and h) lipid at 1390, 1450, and 1390 cm−1, (i) representative absorption spectrum of A549 clones and cancer cells of one experiment. *Significantly different at P< 0.05, **significantly different at P< 0.005. AU: Arbitrary unit
