About Egg Yolk Lecithin
Lecithin was first isolated from egg yolk and the brain by Golbey some 170 years ago, and was called “lecithin” after the Greek word “lekitos,” meaning egg yolk. In ancient times lecithin referred to as phosphatidylcholine, but today it is used as a generic term for the group of lipid products that include phospholipids.
