Kinetic signatures of acylcarnitines.

<p>Kinetic signatures of the 11 selected acylcarnitines are depicted. Dynamic curves were characterized by polynomial fitting of 9^th degree to the median concentration values of the analyzed metabolites. For visualization, relative changes (in %) of metabolite concentrations in reference to their initial concentration at rest are displayed. An early response pattern is shown for valerylcarnitine (C5) with a decrease in relative concentration of approx. 16%. Late response profiles include acetylcarnitine (C2), propionylcarnitine (C3) and butyrylcarnitine (C4).
