11α-hydroxy Testosterone

睾酮testosterone

　　C19 H28 O2 。为 17β -羟基 -4-雄烯 -3-酮。是从牛睾丸中提出的甾体，一般来讲，是睾九分泌的雄性激素的代表物质。在睾丸内是由雄烯二酮经 17β -羟甾体脱氢酶或由 5-雄烯 -3β， 17β二醇经△ 5 -3，β -羟甾体脱氢酶和△ 5 －△ 4 -异构酶的作用所生成。进入副性腺等细胞内形成 5α -二氢甾体，显现出雄性激素的作用。 17-α -羟化物亦称为表睾酮，与 17β体比较雄性激素作用很弱。作为丙酸酯的诱导体可供医疗上使用。 17α

Analysis of Testosterone in Serum Using Mass Spectrometry

For either gas chromatography mass spectrometry (GC-MS) or liquid chromatography tandem mass spectrometry (LC-MS-MS) methods, the first step in the analysis is to add a deuterium-labeled internal standard such as testosterone-16,16,17-d3

Thin-Layer Chromatography Analysis of Human CYP3A-Catalyzed Testosterone 6-Hydroxylation

Testosterone and other steroid hormones have been studied as prototypic examples of endogenous substrates for hepatic cytochrome P450 (P450) enzymes. CYP3A enzymes from various species, including human, metabolize testosterone by a 6β
