Lecithin

A phospholipid. A key structural component of cell membranes, it is also involved in the movement of cholesterol in the body and some brain functions. Available through dietary sources such as eggs yolks, soy, wheat germ, peanuts and liver. Commercial lecithin is isolated from soy and egg yolk and is used in cosmetics as a non-toxic surfactant and emollient, for its emulsifying and lubricant properties. See Phospholipid.
