Answer:
The answer is energy storage.
Step-by-step explanation:
Lipids are a set of organic molecules, which consist mainly of carbon and hydrogen and, to a lesser extent, oxygen. Lipids fulfill diverse functions in living organisms, including energy reserve. Lipids (usually in the form of triacylgeroles) constitute the energy reserve for late or deferred use of the organism. Their caloric content is very high (10 Kcal / gram), and they represent a compact and anhydrous form of energy storage.
