a study of the relative activity of the purified placental nad- and nadp-linked 15-hydroxyprostaglandin dehydrogenases with various prostaglandins and thromboxane b2 ( txb2 ) suggests that most , if not all , oxidation in the placenta of the 15-hydroxyl group of prostaglandins of the a , e , and f series as well as pgi2 ( prostacyclin ) and 6-keto pgf1 alpha is catalyzed by the nad-linked enzyme .
