the major form irreversibly reduced 5 alpha- and 5 beta-dihydrotestosterones , menadione and lauryl aldehyde with low km values of 10-70 microm , whereas the minor form not only reduced 17-oxosteroids , of which 3 alpha-hydroxy-5 beta-androstan-17-one was the best substrate , but also oxidized 17-hydroxysteroids in the presence of nadp+ .
