SEM, standard error of the mean; D × T, Diet × Time; C0, free carnitine; C3, propionylcarnitine; C3-DC, malonylcarnitine; lysoPC a, lysophosphatidylcholine with acyl residue C; SM (OH) C, hydroxysphingomyelin with acyl residue sum C; SM C, sphingomyelin with acyl residue sum C. Values are presented as least square means ± SEM; control diet, n = 6; TGS diet, n = 7. Means with different superscript letters within a row differed significantly (p < 0.05) over all sampling time points. Means with different capital superscript letters tended to differ (0.05 < p ≤ 0.10) over all sampling time points.
