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. Here is a look at different types of lipids and where they are found. 1  Triacylglycerols or Triglycerides.
The four types of lipids are triglycerides, fatty acids, phospholipids, and sterols (cholesterol). Triglycerides are important for metabolism and production of energy.Fatty acids are used to make lipids in cells, attatch to phosphate groups to form phospholipids, and they are used for storage. Phospholipids are the main part of cell membranes and assist in regulating cell environment.riglycerides are important for metabolism and production of energy.
