Combined, our 2 H NMR and DSC results can be interpreted in the following way. As described in the first part of this manuscript, at high temperatures (T ≤62 • C), the C30d/DMPC sample contains n-alkane mixed with the lipid, but also roughly 10 % of bulk alkane. If the sample is cooled, bulk C30d crystallizes first, followed soon after by a fraction of the C30d molecules inside the DMPC membrane as shown by the DSC curves. The fraction of crystallizing chains can be determined by comparing the DSC transition enthalpies of the mixture with the bulk transition enthalpies. By integrating the (rotator-to-liquid) melting peak we find that the melting enthalpy of C30d in DMPC amounts to roughly 81±3% of the bulk C30d melting enthalpy. Therefore, 19±3% of C30d molecules do not crystallize in the mixture. These noncrystallizing chains will be discussed further below.
