We previously showed that the lecithin:cholesterol acyltransferases (LCATs) of susceptible species such as rabbit, pig, and chicken (group I) differ in their substrate and positional specificities from the LCATs of resistant species such as rat and mouse (group II). However, the relative importance of enzyme specificity and substrate phosphatidylcholine (PC) composition in determining the CE composition is not known. To address this, we analyzed the molecular species composition of plasma PC in the same 14 vertebrates in which we previously studied the CE composition and LCAT specificity. The utilization of native PC species by LCAT was studied by determining the loss of each PC after incubation of plasma at 37 degrees C. The major contributor for LCAT reaction was either 16:0-18:2 PC or 18:0-18:2 PC in all species except dog, in which it was 18:0-20:4 PC. The formation of 20:4 CE correlated more with the consumption of 18:0-20:4 PC in group I, and with the consumption of 16:0-20:4 PC in group II. The group II enzymes exhibited higher selectivity for sn-2-20:4 PCs, whereas the group I enzymes showed preference for sn-2-18:2 PCs. The synthesis of high percentage of 20:4 CE in dog plasma was found to be due to the presence of unusually high concentration of 18:0-20:4 PC, rather than due to enzyme selectivity. These results show that the PC molecular species composition, especially the concentrations of sn-2-20:4 phosphatidylcholines has profound influence on plasma CE composition, and possibly on atherogenic risk."xsd:string |
