  1. Endogenous FFA and 13C-labeled FFA were determined in fetal perfusates after 90 min. Results are adjusted to average perfused cotyledon mass (25 g) and are expressed as mean (± SD) µmol/90 min of perfused lean (n = 6) and obese (n = 6) placentae. Differences in endogenous FFA and 13C-FFA were tested between lean and obese placentae (Mann–Whitney U test, * p < 0.05).
