應用^(2)H NMR研究含磷脂及固醇膜的相圖

The determination of the phase diagram of phospholipid/sterol membranes using deuterium NMR

摘要


運用^2H NMR方法可研究含麥角固醇(ergosterol)膜的相態,以及溫度─麥角固醇濃度的相圖。最重要的是,可以明確地定義出相圖中兩種液態共存的區域。此種決定相圖的方法可應用於其他含固醇類的膜樣品。

Deuterium NMR is used to explore the phase behavior of membranes containing phospholipids and ergosterol. The temperature-ergosterol mole fraction phase diagram constructed from the NMR data will be discussed. Our approach to analyzing the NMR spectra has allowed us to definitively locate and characterize the region where two liquid crystalline phases coexist. The general methodology for phase boundary determination in phospholipid/sterol membranes is presented.
