چکیده انگلیسی
The number of water molecules bound (unfreezable) by a molecule of dipalmitoyl phosphatidylserine (DPPS) or by a molecule of dipalmitoyl phosphatidylcholine (DPPC) alone or in mixtures with cholesterol was determined by differential scanning calorimetry (DSC). When the phospholipids are in the gel state and in the absence of cholesterol, molecule of DPPS binds about 3.5 molecules of water and molecule of DPPC binds about 6 molecules of water. Number of water molecules bound increases when cholesterol crystallites are formed in the bilayer. For DPPS-cholesterol mixture at X(chol) â0.5, as well as for DPPC-cholesterol mixture at X(chol) -0.5 about 7 water molecules are bound.
