The hydrolysis of 21-hydroxypregnenolone of fetal origin by steryl-sulfatase (SOS, EC 3.1.6.2), may be important in the biosynthesis of deoxycorticosterone, which is present in the plasma of pregnant women in high concentration. 21-hydroxypregnenolone has been identified in follicular fluid from follicles of women. Pregnenolone is transformed to 21-hydroxypregnenolone by human adrenal microsomal preparations, suggesting the involvement of alternative paths via 17a,21-dihydroxypregnenolone in human.
