Lecithin

Lecithin

Lecithin is a generic term to designate any group of yellow-brownish fatty substances occurring in plant tissues composed of phosphoric acid, choline, fatty acids, glycerol, glycolipids, triglycerides, and phospholipids (e.g., phosphatidylcholine, phosphatidylethanolamine, and phosphatidylinositol).

Lecithin can be extracted chemically (using hexane) or mechanically from readily available sources such as soy beans. It has low solubility in water.
