👉 Phosphatidylcholine (also known as choline) is a type of bilayered lipid molecule found in the cell membrane. It plays a crucial role in the transport of fatty acids and other molecules between the cells, as well as in signaling pathways within cells. In simple terms, phosphatidylcholine is an essential component for the functioning of many cellular processes including cell division, energy production, and signal transduction. Its presence determines the shape and function of the cell
