Lipids are a diverse group of fat-soluble biological molecules. Here is a look at different types of lipids and where they are found. 1  Triacylglycerols or Triglycerides.2  The largest class of lipids goes by different names: triacylglycerols, triglycerides, glycerolipids, or fats.ipids are a diverse group of fat-soluble biological molecules.

Key Concepts: 1  Biological membranes are organised in small, dynamic and transient domains called lipid rafts. 2  Lipid rafts exist in all eukaryotic cells, mostly in the plasma membrane. 3  Lipid rafts are enriched in sphingolipids and sterols, and depleted in phosphoglycerolipids.
