Detailed explanation-1: -Answer and Explanation: The characteristics of lipids are that they are hydrophobic, made of hydrocarbon chains, are good stores of energy for cells, and can be saturated or unsaturated.
Detailed explanation-2: -Triglyceride is the most common lipid that is used for energy storage. Triglycerides are the main body fat constituents for vertebrates. They are tri-esters comprising a glycerol molecule that is bound to three fatty acid molecules.
Detailed explanation-3: -Lipids are used as energy storage via fatty acids. Fatty acids are composed of carboxylic acids attached to long chains of hydrocarbons. These are carbons that can range from 4 to 36 carbons.
Detailed explanation-4: -Just like the carbon-carbon and carbon-hydrogen bonds in glucose allow that molecule to store energy, the bonds in fatty acids allow triglycerides to store energy. In fact, triglycerides can store much more energy than carbohydrates because they contain so many more bonds!
