Figure 2

XRD diffractograms of Cer/FFAs/Chol/CholS membranes containing either sphingosine (Cer NS, Cer (R)–AS, or Cer (S)–AS; Panel (A) or dihydrosphingosine (Cer NdS, Cer (R)–AdS, or Cer (S)–AdS; Panel (B) or phytosphingosine Cers (Cer NP, Cer (R)-AP, or Cer (S)–AP; Panel (C) at ambient room humidity. Intensity is given in arbitrary units (a.u.). Roman numerals mark the La phase (d = 5.3–5.6 nm); Arabic numerals mark the Lb phase (d = 4.3 nm); letters belong to the phase of crystalline Cer NP (d = 3.7 nm); asterisks mark separated Chol (d = 3.4 nm).
