Here's why:
* Lipids are a broad category of organic compounds that are characterized by their insolubility in water and solubility in non-polar solvents.
* Fats and oils are both triglycerides, meaning they are composed of glycerol molecules attached to three fatty acid chains. The difference between fats and oils is their state of matter at room temperature - fats are solid while oils are liquid.
* Waxes are similar to fats and oils in their chemical structure, but they have longer fatty acid chains and are typically more solid at room temperature.
So, while each has unique properties, they all share the common characteristic of being lipids.
