Figure 4From: Thermotropic phase behavior and headgroup interactions of the nonbilayer lipids phosphatidylethanolamine and monogalactosyldiacylglycerol in the dry stateRatio between the fitted peak areas of the two component bands of the carbonyl stretching peaks shown in Fig. 3. The ratio A C=OH-bonded/A C=Ofree, indicating the relative amount of H-bonding to the lipid C=O groups, is shown for the pure lipids and all binary mixtures. The values represent the means ± SE from at least 3 different samples.Back to article page
