What are some characteristics of fats?

Fats, also known as lipids, are organic compounds that are primarily composed of carbon, hydrogen, and oxygen. They are hydrophobic, meaning they do not dissolve in water, and are typically solid at room temperature (saturated fats) or liquid (unsaturated fats). Fats serve several essential functions in the body, including energy storage, insulation, and protection of vital organs. Additionally, they play a crucial role in cell membrane structure and the absorption of fat-soluble vitamins.
