COX-2 exhibits a greater preference for linoleic acid than does Cox-1 and is therefore credited with producing most of these products in cells expressing both COX enzymes.
COX-2 ispoljava znatniju preferenciju za linoleinsku kiselinu nego Cox-1 i stoga je zaslužan za produkciju najvećeg dela tih produkata u ćelijama koje izražavaju oba COX enzima.
