一般說明
烯胆甾烷醇是存在于人母乳中的胆固醇代谢物。烯胆甾烷醇由烯胆甾烷醇5-去饱和酶分解为7-脱氢胆固醇,这是胆固醇的前体。烯胆甾烷醇-d7是烯胆甾烷醇的氘代衍生物。
應用
烯胆甾烷醇-d7已被用作用于母乳甾醇定量的气相色谱-质谱(GC-MS)的内标物,和液相色谱-高分辨率质谱(LC-HRMS)分析的内标物。
生化/生理作用
烯胆甾烷醇水平是胆固醇水平的直接指标,有助于解码代谢缺陷。烯胆甾烷醇水平升高与脑腱黄瘤病(CTX)和烯胆甾烷醇病有关。烯胆甾烷醇5-去饱和酶(SC5D)失活导致烯胆甾烷醇在烯胆甾烷醇病病理学中积累。

Lathosterol 5-desaturase catalyzes the conversion of lathosterol to 7-dehydrocholesterol in the next to last step of cholesterol synthesis. Inborn errors of cholesterol synthesis underlie a group of human malformation syndromes including Smith-Lemli-Opitz syndrome, desmosterolosis, CHILD syndrome, CDPX2 and lathosterolosis. We

The analysis of blood for β-sitosterol and campesterol is the measures of cholesterol absorption while lathosterol is a measure of cholesterol synthesis. The biological variability of β-sitosterol, campesterol, and lathosterol was measured using liquid-chromatography tandem mass spectrometry from a cohort
