Lipids are composed of carbon, hydrogen and oxygen atoms, and in some cases contain phosphorus, nitrogen, sulfur and other elements.

What do lipids contain?

Lipids contain carbon, hydrogen and oxygen but have far less oxygen proportionally than carbohydrates. Lipids are an important part of living cells. Together with carbohydrates and proteins, lipids are the main constituents of plant and animal cells. Cholesterol and triglycerides are lipids.

Where is carbon found in lipids?

Carbon is unique in its ability to form large, diverse molecules like lipids. Like all organic molecules, a lipid consists of a carbon atom “skeleton” to which other molecules are attached. When glycerol (a type of alcohol) and fatty acids are attached to the carbon skeleton, a lipid is made.
