a stoichiometric ratio between net estrogen oxidation and net pg h2 formation of approximately 2:1 for monophenolic compounds ( 2-meoe2 , e2 ) and of 1:1 for diphenolic estrogens ( des , 2-ohe2 ) was found , indicating that estrogens are apparently acting as electron donors for the phs-peroxidase .
