Cellsome®-Natural saturated PC extract catalog is composed of four liposomes made from phosphatidylcholine (PC) lipids. These lipids are from natural lipids that are extracted from either egg yolk or soybean. The unsaturated natural extracted lipids go through hydrogenation process and fully saturated lipids are made and the liposomes are formulated from these hydrogenated lipids with and without cholesterol. Adding 30% cholesterol makes the liposomes serum stable and is necessary when the liposomes are used in the presence of serum.

Hydrogenated soy PC is composed of mainly two saturated lipids:  88.6% of 18:0 lipid and 11.4% of 16:0 lipid.

Hydrogenated egg PC is composed of mainly five saturated lipids: 0.1% of 14:0 lipid, 32.2% of 16:0 lipid, 60.6% of 18:0 lipid, 4.5% of 20:0 lipid, and 2.2% of 22:0 lipid.
