Abstract
Proton resonance spectroscopy was used to determine the state of the hydrocarbon regions in lyophilized and resuspended samples of nerve myelin. Measurements of the resonance line width indicate considerable freedom of motion within the hydrocarbon moiety of the myelin samples. Sharp thermal transitions of the line width were observed, suggesting that lyophilized myelin is in a liquid crystalline state.
摘要
质子共振光谱法被用于测定神经髓鞘冻干和重悬样品中烃区域的状态。共振线宽的测量表明髓鞘样品的烃部分内存在相当大的运动自由度。观察到线宽有明显的热转变，这表明冻干的髓鞘处于液晶状态。
