Lipids can be described as hydrocarbons which are only soluble in non-polar solvents like chloroform. Lipids are non-polar and are insoluble in water. Lipids serve s an excellent source of energy storage and energy is stored in the body of organisms due to these non-polar molecules. Energy is usually stored as triglyceride which is a type of lipid. Triglycerides contain glycerol and fatty acids. Fats and oils are examples of lipids.
