Explanation:

As well as carbohydrates, lipids also contain carbon, hydrogen and oxygen (since they have a hydrocarbon chain and glycerol backbone)

Proteins can also contain nitrogen atoms (amino acids); proteins also have an 'R' group; proteins also are folded structures

Lipids also have fatty acid chains and glycerol
