Lecithin is a mixture of phospholipids, glycolipids, glycerides, and other minor components. It is due to its high phospholipid content that lecithin possesses specific functions. Phospholipids are amphiphilic, meaning they have different affinities for oil and water. Lecithin forms stable O/W and W/O emulsions and durable dispersions in a wide range of applications. It is generally found in all living cells as a major component of the cell membrane, which regulates the nutrients entering and exiting the cell or the metabolic processes. Lecithin is a vital feature of all life; it is an essential nutritional supplement.
