General description
已知7α-羟基-4-胆甾烯-3-酮（C4）是胆固醇7α-羟化酶活性的标志物。在胆汁酸代谢中起重要作用。
Application
C4可作为参比标准品，
- 通过超高效液相色谱-串联质谱法（UHPLC-MS / MS）-电喷雾离子源（ESI）测定人血清中的C4。
- 通过LC-ESI-MS / MS进行多反应监测（MRM）模式检测的大鼠和猴血浆。
- 采用固相萃取（SPE）和HPLC测定外周血血浆。
Biochem/physiol Actions
7a-羟基胆甾-3-酮是胆汁酸合成中的代谢产物，来源于 7a-羟基胆固醇，可进一步代谢为 7a,12a,-二羟基胆甾-4-烯-3-酮，用于分析分析血清中 7a-羟基胆甾烯-3-酮 (HCO) 可能作为一种新型、简便、灵敏的方法用于检测不明原因慢性腹泻患者的胆汁酸吸收障碍。
