Table 1.

Band positions and tentative assignments for human normal colon cells from control sample, in oxidative stress conditions generated by adding tBuOOH (discussed later in the manuscript) and for the experiments for vitamin C supplementation. Data based on the average Raman spectra for cells as a whole measured in PBS, excitation laser line 532 nm [41,42].
