Solubility of phospholipid polar group model compounds in water.
The aqueous solubilities of the Na+ and Ca2+ salts and the free acid forms of phosphorylcholine, phosphorylethanolamine and D,L-phospho-serine, respectively, were found to be below the polar group concentrations calculated for bilayers of the corresponding phospholipids.
