title: Cortisol: a tool to study aldosterone biosynthesis in rats.
abstract: Corticosterone (B) and 18-hydroxy-11-deoxycorticosterone (18OHDOC) but not 11-deoxycorticosterone (DOC) displaced cortisol (F) specifically bound to rat adrenal mitochondria. F. competitively inhibited aldosterone formation from B, 18OHB and 18OHDOC but did not inhibit conversions of DOC to B or 18OHDOC. High concentrations of DOC increased its conversion to 18OHDOC rather than B.
