Placental Transport of Retinol in Sheep

The Journal of Nutrition, 1982
Six ewes in the last trimester of pregnancy were maintained on adequate intakes of vitamin A. Indwelling catheters were implanted surgically in fetal jugular veins and carotid arteries. Three ewes and three fatal lambs received intravenous [15-3H] retinol 19 days prior to parturition, followed by sequential sampling of maternal and fetal blood.

Transport and uptake of retinol during chicken oocyte growth

Lipids and Lipid Metabolism, 1993
Most, if not all, components found in the yolk of a chicken egg are extracted from the plasma compartment during the rapid growth phase of the oocyte. Uptake of the major yolk constituents, very-low-density lipoprotein and vitellogenin, has been shown to be mediated by a specific receptor in the plasma membrane of the oocyte (Barber, D.L., Aebersold, R.

Human serum retinol transport in malabsorption

The American Journal of Clinical Nutrition, 1974
Using specific immunoassays for retinol-binding protein (RBP) and prealbumin (PA), the proteins responsible for serum vitamin A transport in man, the retinol transport system has been examined in 22 adults with malabsorption (mean stool fat 23 g/24 hr). Mean serum concentrations of vitamin A and RBP in these patients did not differ from normal, whereas
