trans-Arachidonic Acids. — Hepatic microsomes oxidize trans-arachidonic acids, products of cis-trans isomerization of arachidonic acid by nitrogen dioxide radical, via cytochrome P-450/NADPH system to epoxides, which are hydrolyzed by epoxide hy-drolase to diols. The reactions are carried out with radio- and deuterium-labeled sub-stances, the products are analyzed by HPLC with a radio detector or by GC-MS. — (ROY, U.; LOREAU, O.; BALAZY*, M.; Bioorg. Med.
