Background - F2 isoprostanes are stable, free radical-catalyzed products of arachidonic acid that reflect lipid peroxidation in vivo. Methods and Results - Specific assays were developed by use of mass spectrometry for the F2 isoprostanes iPF(2α)-III and iPF(2α)-VI and arachidonic acid (AA). Urinary excretion of the 2 F2 isoprostanes was significantly increased in hypercholesterolemic patients, whereas substrate AA in urine did not differ between the groups. iPF(2α)-III (pmol/mmol creatinine) was elevated (P2-III in LDL and urine were significantly correlated (r=0.42; P
