Lipides naturels are biochemical compounds, and many of them are important components of cell membranes or play roles in various biochemical processes. They are not typically used as commercial biochemical products in the way that enzymes, reagents, or other lab chemicals might be. However, they are valuable in biological research, biotechnology, and medicine.for instance: 

1. Cerebroside: A glycosphingolipid involved in cell membrane structure.

2. Glycerophosphorylcholine: A phosphorylated glycerolipid with a choline head group.

3. Phosphatidylcholine: A major phospholipid in cell membranes with a choline head group. Often used in liposome formulations.

4. Lysophosphatidyl Ethanolamine: A lysophospholipid with an ethanolamine head group.

5. Phosphatidic Acid: An intermediate in the synthesis of other phospholipids.

6. Phosphatidylethanol: A phospholipid with an ethanol head group.

7. Phosphatidylethanolamine: A phospholipid with an ethanolamine head group, involved in membrane structure.

8. Phosphatidylglycerol: A phospholipid with a glycerol head group, contributing to membrane organization.

9. Phosphatidylinositol: A phospholipid with an inositol head group, involved in cellular signaling.

10. Phosphatidylpropanol: The term is not commonly used or recognized in standard biochemical nomenclature.

11. Phosphatidylserine: A phospholipid with a serine head group, involved in cell signaling and apoptosis.

12. Sphingomyelin: A sphingolipid with a phosphorylcholine head group, important for membrane structure.

13. Sulfatide: A sulfated galactocerebroside, a type of glycosphingolipid.

These compounds are often used in research laboratories for studying membrane biology, lipid metabolism, and signal transduction. They may also have applications in pharmaceuticals and biotechnology, particularly in the development of liposomal drug delivery systems and other lipid-based formulations.
