Cellsome®-Natural PC extract catalog is composed of many liposomes made from phosphatidylcholine (PC) lipids that are made from natural lipids that are extracted from egg yolk, soybean, tissues and organs such as brain, heart and liver 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.

Liposomes made from egg PC, contain both saturated and unsaturated lipids. These liposomes contain0.2% of the 14:0 lipid, 32.7% 16:0 lipid, 12.3% 18:0 lipid, 1.1% 16:1 lipid, 32% 18:1 lipid, 17.1% 18:2 lipid, 0.2% 20:2 lipid, and 0.3% 20:3 lipid, 2.7% 20:4 lipid and 0.4% 22:6 lipid.

Liposomes made from Brain PC contain both saturated and unsaturated lipids. They contain 0.3% 14:0 lipid, 30.6% 16:0 lipids, 16.5% 18:0 lipid, 0.9% 16:1 lipid, 33.3 % 18:1 lipid, 1.1% 18:2 lipid, 0.8% 20:1 lipid, 0.2% 20:3 lipid, 3.1% 20:4 lipid  and 0.6% 22:6 lipid.

Liposomes made from Heart PC also contain 40% plasmalogen ether lipid. Ether lipids are more stable and do not get hydrolyzed. Heart PC also contains saturated and unsaturated lipids. It contains about 23% 16:0 lipid, 7% 18:0 lipid, 11% 18:1 lipid, 43% 18:2 lipid and 6% 20:4 lipid.

Liver PC also contains saturated and unsaturated lipids. Almost half of the lipids are saturated and the other half unsaturated. It is composed of 14% 16:0 lipid, 33% 18:0 lipid, 17% 18:1 lipid, 12% 18:2 lipid, 8% 20:3 lipid and 7% 20:4 lipid.

Soy PC also contains saturated and unsaturated lipids. Soy PC is mostly composed of unsaturated lipids and have a larger percentage of unsaturated PCs compare to egg, brain, heart and liver extracted PCs. Liposomes made from Soy PC contain 14.9% 16:0 lipid, 3.7% 18:0 lipid, 11.4% 18:1 lipid, 63% 18:2 lipid and 5.7% 18:3 lipid.
