Like carbohydrates, lipids are organic compounds that are high in energy and are made of carbon, hydrogen, and oxygen, but lipids have more energy than carbohydrates. Lipids are stored in cells for later use. Some examples of lipids are oils, fats, and waxes. Cell membranes are also made of lipids.
