Figure 7

The β matrix values for selected liver lipid components. The β matrix values are shown for 8 illustrative lipid molecular species of different functional class and for all internal standards used (abbreviated as shown in Table 1). The LPC has expectedly high influence on monoacyl lipids. As one would have expected based on chemical structure, the sphingomyelin, which does not have its own class-specific internal standard, is influenced most by ceramide (Cer) and phosphatidylcholine (PC) standards
