Structure and Phase Behavior of Synthetic Ceramide 2 ((2S,3R)-2-Octadecanoylamino-octadecane-1,3-diol) ant Its Interaction with Limonene

Abstract

In this study, we studied the structure and phase behavior of synthetic ceramide 2 ((2S,3R)-2-Octadecanoylamino-octadecane-1,3-diol) (S-CER2) using differential scanning calorimetry (DSC) and X-ray diffraction. In addition, we also investigated the effects of limonene on S-CER2. It was found that the phase behavior of S-CER2 depends on its thermal history and that the DSC thermograms depend apparently on the scan rates. The present study suggested a relatively strong affinity between limonene and S-CER2.
