Mean intensities ± SD of metabolic trajectories (over 120 min) for 2-hydroxy-2-methylbutanoic acid (A), 2-hydroxyvaleric acid (B), 2-ketoisocaproic acid (C), 3-hydroxybutyric acid (D), 5-methoxytryptamine (E), acetoacetate (F), aconitic acid (G), adenosine-5-monophosphate (H), α-aminoadipic acid (I), α-ketoglutarate (J), aminomalonate (K), and aspartic acid (L). These metabolites indicated significant (P value < 0.05) overall treatment effects for AUCs (Table 1) in late-fasted elephant seals. LDG, n = 3 seal pups; HDG; n = 4 seal pups; control, n = 5 seal pups. Values are unadjusted and nontransformed.
