The hydroxylation at C-2 of testosterone and 5alpha-dihydrotestosterone is measured by isolation of HTO after incubating "metabolically labile" tritium labeled steroids with the enzymes. After hydroxylation of testosterone in rat liver 2alpha-hydroxytestosterone was isolated and identified by gaschromatography and mass spectra.
通过将“代谢不稳定”的氚标记类固醇与酶一起孵育后分离出HTO,来测定睾酮和5α-二氢睾酮在C-2位的羟基化情况。在大鼠肝脏中睾酮发生羟基化反应后,通过气相色谱和质谱法分离并鉴定出了2α-羟基睾酮。
