While formulating liposomes, I use soybean lecithin as a phospholipid. what is the ideal phosphatidylcholine content in highly pure soybean lecithin that assure it’s solubility in ethanol, liposome formation and good encapsulation?
Its depend on source of Lecithin.
Evergreen's Sunflower Lecithin, made from non-GMO sunflowers, is a natural source of choline, inositol, omega-6 and omega-3 fatty acids. The phosphatidylcholine content is about 10.5% or 1.6 grams per serving.
The phospholipid composition of soya bean lecithin on an oil‐free basis is 21% phosphatidylcholine, 22% phosphatidylethanolamine, 19% phosphatidylinositol, 10% phosphatidic acid, 1% phosphatidylserine and 12% glycolipids
The main Phospho lipids in soybean lecithin are phosphatidylcholine (PC), 55.3%;
phosphatidylethanolamine (PE), 26.3%; and phosphatidylinositol (PI), 18.4%
