β¦ Synopsis
The interaction of cholesterol with a series of saturated phosphatidylglycerols was investigated using differential scanning calorimetry and X-ray diffraction. We find that the miscibility of cholesterol in phosphatidylglycerol bilayers is lower than in the corresponding phosphatidylcholine bilayers and decreases with increasing acyl chain length of the phospholipid. The influence of the negative charge of the phosphatidylglycerol on cholesterol miscibility is discussed.

The phase behavior of aqueous mixtures of gelatin and oligosaccharides above their gelation temperature is investigated experimentally, and rationalized according to a simple multicomponent Flory-Huggins model. When the gelatin is only weakly charged, entropic considerations dominate and it is found
