Lipid
An energy-rich organic compound such as a fat or oil
Real World Example
Imagine trying to pack a suitcase for a long trip, where space is limited, and you need to fit as much as possible. Lipids, like fats and oils, act like highly efficient packers in your body's energy suitcase, storing a large amount of energy in a compact space. Just as you might roll clothes tightly to maximize space, lipids store energy densely, making them an energy-rich resource that can be easily accessed when needed.
