title: [Polyunsaturated phosphatidylcholine and bile lipid composition].
abstract: The lipid composition of bile and the molar percentages of its components (cholesterol, lecithin [Lec], and bile salts) are influenced by diet composition (for example the content of cholesterol) and during fasting. Molecular species of Lec can be affected by the species of dietary fatty acids (a high n-3 fatty acid content in the diet increases their proportion in biliary Lec). The administration of polyunsaturated Lec (EPL), rich in 18:2-18:2-PC, increases the percentage of linoleic acid at position 2 of biliary lecithin, which is often reduced in subjects with cholesterol gallstones.
