Lipids are energy-rich organic, non-polar molecules. These organic compounds contain carbon, hydrogen and oxygen atoms that form a framework for the structure and function of living cells. They are insoluble in water and only soluble in nonpolar solvents as water is a polar molecule. These molecules in the human body can be synthesized in the liver and are typically found in butter, whole milk, oil, cheese, food that is fried and in so,e red meats too.
