Description_x000D_ General description_x000D_ L-α-Phosphatidylcholine (PC) is an asymmetric molecule with glycerol backbone and occurs naturally in lecithin of egg yolk. It is a phospholipid and major choline source in mammalian cells. It is crucial for very low-density lipoprotein secretion in hepatocytes. It is essential for the acetylcholine synthesis functions to nourish the brain. PC plays a crucial role in lipid and lipoprotein metabolism. Deficiencies of enzymes in PC biosynthetic pathway leads to an array of metabolic disorder. Intracellular levels of hepatic PC to phosphatidylethanolamine (PE) ratio contributes to pathophysiology non-alcoholic fatty liver disease (NAFLD). It has anti-inflammatory functionality and is effective in treating inflammatory bowel disease. PC administration therapy is effective for treating benign symmetric lipomatosis._x000D_ Application_x000D_ L-α-Phosphatidylcholine has been used:_x000D_ • for liposome preparation_x000D_ • as a component of stabilizer solution for preparing dispersed curcuminoid submicron particle (CSP)_x000D_ • as a component of serum free substitute for whole blood cells_x000D_ Biochem/physiol Actions_x000D_ A major structural phospholipid in brain, comprising approx. 15% of total lipid; primarily localized to gray matter._x000D_ Packaging_x000D_ Packaged under Argon_x000D_ Preparation Note_x000D_ Prepared by a modification of the procedure of Singleton, W.S., et al., J.
