Abstract
Using isotope dilution mass spectrometry, 26-hydroxycholesterol was identified in the serum of normal adults. Total values ranged from 9.2 to 25.6 micrograms/100 ml of which 31-35% was free sterol. Density gradient ultracentrifugation indicates that the steroid is distributed among the low and high density lipoproteins.
摘要
采用同位素稀释质谱法，在正常成年人血清中鉴定出了26-羟基胆固醇。总量范围为9.2至25.6微克/100毫升，其中31 - 35%为游离固醇。密度梯度超速离心表明，该类固醇分布于低密度脂蛋白和高密度脂蛋白中。
