FFA content in control and PLA₂-treated LDL samples after fatty acid supplementation

	FFA Mix
Sample	0 mM	0.04 mM	0.2 mM
Control	−0.015 ± 0.0003	0.003 ± 0.000	0.010 ± 0.0049^a
PLA₂	0.141 ± 0.0387	0.169 ± 0.0599	0.224 ± 0.0044^a

LDL samples were incubated with the indicated concentrations of fatty acid mixture [oleic, linoleic, and arachidonic acid (20:40:10)] for 4 h, and the unbound material was removed by ultracentrifugation in the presence of 1% BSA. Data show higher enrichment of PLA₂-LDL samples with unesterified fatty acids. Values are expressed as μmol/mg LDL protein.

P < 0.05 compared with 0 mM FFA concentration.
