Tristearin is a molecule composed of glycerol attached to 3 fatty acids. It stores energy and, when broken down, delivers fatty acids to the bloodstream to be used throughout the body.The presence of which of the following structural characteristics allows this molecule to effectively store long-term energy?

Tristearin has three long fatty-acid chains made mostly of carbon and hydrogen. The many energy-rich bonds in these chains release energy when the molecule is broken down, making them effective for long-term energy storage. The glycerol molecule connects the fatty acids, but the carbon chains are the key energy-storing feature.
