What is the difference between Lecithin and Phosphatidyl Choline (PC)?
Lecithin is a group of fatty substances including phospholipids (phosphatidylcholine (PC), phosphatidylethanolamine and phosphatidylinositol), glycolipids and triglycerides. Phosphatidyl Choline is one of the active materials extracted from the Lecithin. Sometimes, Lecithin is used as a synonym for pure PC. Example: Lecithin 40%, which actually refers to 40% of PC instead of 40% Lecithin.
