Abstract
The placenta is an organ that exchanges heat and matter between the fetal and maternal circulations. This exchange is the principal means by which the placenta controls fetal metabolism. This review will focus on the placental exchanges of nutrient substrates and how these affect fetal energy and protein metabolism. Other interesting aspects of placental exchange and control of fetal metabolism such as exchange of vitamins, macro-minerals, trace elements and “essential growth factors” (e.g. inositol, choline), as well as placental blood flow and the processing of various hormones (e.g. progesterone, oestrogen, placental lactogen) are equally important but beyond the scope of this review. Most of the information and concepts presented reflect animal experimentation given the paucity of data from human studies for obvious technical and ethical reasons.
