Lipids

Lipids are small, organic molecules, that are usually hydrophobic or amphiphillic. For example, this group includes fats, fatty acids, waxes, triglycerides, sterols and phospholipids. Lipids are the main structural component of biological membranes of all cells. As such, bacterial lipid structures and glycolipids can serve as pathogen-associated molecular patterns (PAMPs) and are recognized by the human immune system. Various lipids and lipid complexes of bacterial origin are therefore used as immunostimulants.
