Palmitoylcarnitine lowers glutathione redox buffering capacity in HT29 cells but not CCD 841 cells. The following parameters of glutathione redox buffering were assessed after 24 and 48 h of palmitoylcarnitine, respectively: ratio of reduced to oxidized glutathione (GSH/GSSG, A and B), reduced glutathione (GSH, C and D), oxidized glutathione (GSSG, E and F), and total glutathione (tGS, G and H) (N = 5). Data are reported as means ± SE. *P < 0.05, significant difference relative to 0 µM palmitoylcarnitine of the same cell type.
