在这里,我们使用核磁共振测量的溶解度极限的几个生物相关的甾醇在电铸巨单层囊泡膜含有磷脂酰胆碱(PC)脂质的比例为1:1:X DOPC:DPPC:甾醇。我们发现胆固醇、羊毛甾醇、麦角甾醇、豆甾醇和β-谷甾醇的溶解度极限分别为65- 70%、~ 35%、30- 35%、20- 25%和~ 40%。豆甾醇和β-谷甾醇的低溶解度与胆固醇的区别仅在于它们的烷基尾部,这表明尾部结构的细微差异可以强烈影响甾醇溶解度。低于溶解度限度,电铸囊泡中甾醇与PC-脂质的比例线性反映了电铸工艺中使用的原始储备溶液中的比例。
Here we use nuclear magnetic resonance to measure the solubility limit of several biologically relevant sterols in electroformed giant unilamellar vesicle membranes containing phosphatidylcholine (PC) lipids in ratios of 1:1:X DOPC:DPPC:sterol. We find solubility limits of cholesterol, lanosterol, ergosterol, stigmasterol, and β-sitosterol to be 65-70%, ~35%, 30-35%, 20-25%, and ~40%, respectively. The low solubilities of stigmasterol and β-sitosterol, which differ from cholesterol only in their alkyl tails, show that subtle differences in tail structure can strongly affect sterol solubility. Below the solubility limits, the fraction of sterol to PC-lipid in electroformed vesicles linearly reflects the fraction in the original stock solutions used in the electroformation process.
