Fig. 5. Specificity of EL for the molecular species of PtdCho in lipoproteins.

Fig. 5

Sphingomyelinase(SMase)-treated or untreated lipoproteins were incubated with EL for 4 h and the PtdCho molecular species composition was analyzed as described in Materials and Methods. The decrease in individual PtdCho species after EL treatment was determined (compared to control sample incubated in the absence of EL) from this data. The relative specificity was calculated by dividing the contribution of individual PtdCho species to the decrease in total PtdCho (in %) by the concentration of the same species (% of total) in the untreated sample. A value above 1.0 indicates that the given PtdCho species is preferentially hydrolyzed by EL. The values shown are averages of 2 experiments.
