Metabolism studies. GC-MS is a powerful technique for following and identifying the metabolic products from the in vitro incubation of tissue preparations with steroid substrates. Examples of such studies include the 16a-hydroxylation of 18-hydroxydeoxycorticosterone by human adrenal gland [254], the eiromatization of 3jS,15, 16 -trihydroxy-5-androsten-17-one by placental homogenates [255], and the demonstration of 1/3, 12/3, 6a and 6/3 hydroxylase enzyme activities in microsomal preparations of human foetal hepatic tissue [256]. In the latter study, testosterone was used as substrate and in addition to the hydroxylated metabolites isolated, several other testosterone derivatives indicated the presence of 3a, 3/3 and 17/3-hydroxysteroid oxidoreductase in the adrenal gland preparation.
