A microscopic interaction model of maximum solubility of cholesterol in lipid bilayers.
We recently reported the equilibrium maximum solubility of cholesterol in a lipid bilayer, chi*chol, to be 0.66 in four different phosphatidylcholines, and 0.51 in a phosphatidylethanolamine (Huang, J.,J.T. Buboltz, and G. W. Feigenson. 1999. Biochim. Biophys. Acta. in press). Here we present a model of cholesterol-phospholipid mixing that explains these observed values of chi*chol. Monte Carlo...
متن کاملMaximum solubility of cholesterol in phosphatidylcholine and phosphatidylethanolamine bilayers.
In any lipid bilayer membrane, there is an upper limit on the cholesterol concentration that can be accommodated within the bilayer structure; excess cholesterol will precipitate as crystals of pure cholesterol monohydrate. This cholesterol solubility limit is a well-defined quantity. It is a first-order phase boundary in the phospholipid/cholesterol phase diagram. There are many different solu...
متن کاملPrediction of Satranidazole Solubility in Water-Polyethylene Glycol 400 Mixtures Using Extended Hildebrand Solubility Approach
The Extended Hildebrand Solubility Parameter Approach (EHSA) is used to estimate the solubility of satranidazole in binary solvent systems. The solubility of satranidazole in various water-PEG 400 mixtures was analyzed in terms of solute-solvent interactions using a modified version of Hildebrand-Scatchard treatment for regular solutions. The solubility equation employs term interaction ...
متن کاملAcetylsalicylic acid (ASA) increases the solubility of cholesterol when incorporated in lipid membranes.
Cholesterol has been well established as a mediator of cell membrane fluidity. By interacting with lipid tails, cholesterol causes the membrane tails to be constrained thereby reducing membrane fluidity, well known as the condensation effect. Acetylsalicylic acid (ASA), the main ingredient in aspirin, has recently been shown to increase fluidity in lipid bilayers by primarily interacting with l...
