Additional file 3: Supplementary Fig. 3 Relative abundances of hexose sugars in maternal and fetal plasma (a,b) and placental fluids (c,d). Glucose and fructose concentrations in plasma are expressed as concentrations (μmol/L), and in placental fluids are expressed as total amounts (concentration × volume). There were greater concentrations of glucose than fructose in maternal plasma (a), in contrast to fetal plasma (b) which had greater concentrations of fructose compared to glucose. Similarly, both allantoic fluid (c) and amniotic fluid (d) had greater total amounts of fructose compared to glucose. Mean values and SEM are presented. n = 5–9 samples per group.
