The peak maximum at large distances for native LDL was rmax 177。 nm, which corresponds to the electron density autocorrelation of the phospholipid headgroups and protein moiety. ? Broadening of maximum peak for LDL control without significant difference in rmax value indicate formation of LDL aggregates during incubation. ? Increase in rmax value (?r=177。 nm) and broadening of peak maximum for LDLDOT indicate slightly increase in the maximum particle diameter and formation of LDL aggregates.
