  • Title: Placental transfer of free fatty acids: importance of fetal albumin concentration and acid-base status.
    Author: Stephenson T, Stammers J, Hull D.
    Journal: Biol Neonate; 1993; 63(5):273-80. PubMed ID: 8353154.
    Abstract:
    Free fatty acids (FFA) are the main class of naturally occurring lipids transferred across the placenta, irrespective of species. In order to study the importance of fetal plasma albumin concentration and pH on placental transfer of FFA, in situ perfusion of the rabbit placenta in late gestation was used as an experimental model. Increasing albumin concentration on the fetal side of the placenta from 1 to 6% significantly increased transfer of FFA across the placenta. However, alteration of the umbilical perfusate pH in the range 7.0-7.5 had no significant effect.
