4,8-DHNA and 4,9-DHNA production in rat brain, heart, kidney, and liver homogenates incubated with HNA via ω-1- and ω-hydroxylation.
A and B, 4,8-DHNA and 4,9-DHNA productions from HNA incubated in rat brain, heart, kidney, and liver homogenates. C, total amount of 4,8-DHNA and 4,9-DHNA production. D, ratio of 4,9-DHNA/4,8-DHNA. Rat organ homogenates were incubated with 1 mm HNA, 1 mm NADPH, and 100 mm phosphate buffer at 37 °C for 30 min. ω- and ω-1-hydroxylation products were assayed by GC-MS. Error bar, S.D. of measurements (n = 5).
