VLCDCA 28:4 levels in the plasma of different species and in different human biofluids. VLCDCA 28:4 levels are presented as R (ratio of endogenous VLCDCA 28:4 peak area to the peak area of 1 nanomole [2H28]dicarboxylic acid 16:0 per 100 μL biofluid). In the cases where VLCDCA 28:4 was not detected in 100 μL biofluid, the negative observations were further validated by extracting 500 μL biofluid. The values are the means of 3 observations. ND, not detected.
