Phosphatidylcholine, commonly referred to as lecithin, is a biologically essential phospholipid primarily extracted from chicken egg yolks and soybean seeds. As an integral component of cell membranes, it plays a pivotal role in maintaining the structural integrity and functional capacity of cells throughout the human body. Its multifaceted effects encompass nutritional benefits—as a source of choline and fatty acids—as well as physiological properties that support lipid metabolism, alongside pharmaceutical and technological applications in the food processing and cosmetics industries.
The properties of lecithin
