Product name: Phosphatidylcholine Assay 60%-90% Description Phosphatidylcholine, one of a primal class of substances ubiquitous among life forms, is the predominant phospholipid of all cell membranes and of the circulating blood lipoproteins and a primary dietary source of choline. PC is composed of a phosphate group, 2 fatty acids, glycerol and choline. The composition of essential fatty acids in phosphatidylcholine determines its value in promoting health. PC is a normal constituent of the bile that facilitates fat emulsification, absorption, and transport, and is recycled via entero-hepatic circulation. Chemical properties Chemical Name: Phosphatidylcholine, Lecithin Molecular Formula: Unspecified Molecular Structure Phosphatidylcholine, CAS: 8002-43-5 R=long chain fatty acids Applications 1. Phosphatidylcholine is known as a penetration enhancer; this property is usually associated with liposomes 2. It is the main functional constituent of the natural surfactants, and the body's foremost reservoir of choline, an essential nutrient.Greater than 98 percent of blood and tissue choline is sequestered in PC and dietary PC serves as a "slow-release" blood choline source 2. Methyl deficiency induced by restricted choline intake is linked to liver steatosis in humans, and to increased cancer risk in many mammals. PC is an excellent source of methyl groups, supplying up to three per PC molecule 3. PC is the preferred precursor for certain phospholipids and other biologically important molecules and protect against a variety of chemical toxins and pharmaceutical adverse.
