FIG. 4.
Time-dependent decrease of phosphorylated metabolites of l-Hyd4C in HepG2 cells after exposure to 10 μM l-[3H]Hyd4C for 24 h. The concentrations of the 5′-monophosphate, 5′-diphosphate, and 5′-triphosphate of l-Hyd4C are given in pmol/106 cells. The values are means ± standard deviations of results from three independent experiments.
