Merck, P7443-500MG, L-α-Phosphatidylcholine

General description
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.
