FIG. 1.

Effect of G25 on [³H]choline, [³H]ethanolamine, and [³H]hypoxanthine incorporation into PC, PE, and nucleic acids (NA) of P. falciparum-infected erythrocytes. Infected RBC (3.4% hematocrit, 10% parasitemia, Nigerian strain) were incubated for 4 h at 37°C in the absence (control) or presence of G25 and in the presence of 1.5 μCi of [³H]choline (at 10 μM) (•), 0.8 μCi of [³H]ethanolamine (2 μM) (▪), and 1 μCi of [³H]hypoxanthine (trace concentration) (▵).
