The structure that could be found in a lipid, but not in a carbohydrate, protein, or nucleic acid is:
**A long chain made only of carbon and hydrogen atoms (hydrocarbon chain).**
Lipids are characterized by their long hydrocarbon chains, which can be saturated or unsaturated. Carbohydrates, proteins, and nucleic acids do not have structures that consist solely of long chains of carbon and hydrogen atoms. Instead, they contain other functional groups and elements such as oxygen, nitrogen, and phosphorus in their compositions.
