Solution: B. Lipid Lipids are made up of fatty acids that store energy for the long term. Triglyceride famously known as fat, and a form of lipids, is made up of a molecule of glycerol bonded with three molecules of fatty acids. Triglycerides also store up energy efficiently. Other components that make up fatty acids which in turn make lipids are hydrogen carbon and oxygen molecules.
This macromolecule stores energy and is composed of fatty acids, glycerol, and other components. A. Carbohydrate B. Lipid C. Nucleic acid D. Protein
