Webb18 maj 2024 · Lecithin. Lecithin is a phospholipid, a yellow-brown fatty substance that consists of glycerol, two fatty acids, a phosphate group, and choline. Lecithin was first found in eggs in 1846, so its name was coined from the Greek word for egg yolk, lekithos. Though lecithin is its common name, chemists refer to it as phosphatidylcholine.
