the results obtained from these experiments suggest that the first three metabolites were synthesized by a well-documented pathway -- pregnenolone yields 17 alpha-hydroxypregnenolone yields dehydroepiandrosterone yields 5-androstene-3 beta,17 beta-diol -- , and that 16 alpha-hydroxypregnenolone , 5-androstene-3 beta,17 alpha-diol and 5,16-androstadien-3 beta-ol were synthesized from [ 17-2h ] pregnenolone with retention of 17-2h .
