What term describes fats and oils?

The term that describes fats and oils is "lipids." Lipids are a diverse group of compounds that are insoluble in water but soluble in organic solvents. They play several vital roles in biological systems, including energy storage, serving as structural components of cell membranes, and acting as signaling molecules. Fats and oils, which are types of lipids, store energy in a highly efficient form and can also provide insulation and protection for organs.

Understanding the classification of biomolecules is crucial. Carbohydrates are primarily involved in providing energy and structuring cells, while proteins are made up of amino acids and function in numerous roles such as structural support and catalyzing biochemical reactions. Nucleic acids, such as DNA and RNA, are involved in the storage and transmission of genetic information. Hence, only lipids encompass fats and oils among the main types of biological macromolecules.
