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.

All living things contain organic macromolecules: Lipids, proteins, carbohydrates and nucleic acids. Characteristic for these organic molecules is that they are made up of only a small number of elements: carbon, hydrogen, oxygen, and to smaller amounts nitrogen, phosphorus and sulfur. Lipids are also an important component of the cell membrane. 2  Lipids consist of glycerol and fatty acids tails. 3  The fatty acid tails are long chains of carbon and hydrogen that contribute to the non-polar behavior of fats-they don't mix with (polar) water.
