Maternal plasma MPE (mole percent excess) after bolus infusion in control and MNR baboons. (A–I): MPE of stable isotope-labeled (1-¹³C) valine, (1-¹³C) leucine, (1-¹³C) isoleucine, [Methyl-²H₃] methionine, [U-¹³C₄] threonine, [1-¹³C] phenylalanine, [4,4,5,5-²H₄] lysine, [Ring 2-¹³C] histidine, and [Indole-²H₅] tryptophan in maternal arterial blood after intravenous infusion of a mixture of labeled essential amino acids to the pregnant baboon at GD 140 (Control, n = 8; MNR, n = 8). Medians ± IQR, t = 1/2: half-life. Each data point represents combined maternal MPE values of both control and MNR group (n = 16 each time point, (Control, n = 8; MNR, n = 8)).
