Phosphatidycholine is an active ingredient in lecithin. The lecithin acts by increasing the action of enzymes that degrade the lipids of the cell membrane. In fat cells, this action increases the fluidity and permeability of the membrane adipocyte, facilitating the release of fat. Lecithin also increases the solubility of cholesterol. Every cell membrane in the body requires phosphatidylcholine (PC). It is also a major source of the neurotransmitter acetylcholine..
