Uptake of different amounts of triglyceride by the placenta and transport to the fetus. Lyposyn II was radiolabeled with [³H]triolein and injected iv into pregnant dams (18.5 dpc). Triglyceride mass injected was ≈10 or ≈30 μg. Twenty minutes postinjection, fetuses and placentas were collected rapidly and saponified, lipids were extracted, and amount of radiolabel was measured. Data are presented as means ± SE (n = 5 litters) of percent injected (A) and μg lipid taken up (B). *Differences (P < 0.05) between tissues of dams injected with different triglyceride mass.
