Fats are categorized as what type of compound?

Fats are categorized as lipids, which are a diverse group of compounds that are soluble in nonpolar solvents but greatly insoluble in water. This classification includes not only fats, but also oils, waxes, and sterols. Lipids play essential roles in the body, including serving as energy sources, components of cell membranes, and signaling molecules.

In contrast, carbohydrates are primarily sugars and starches and are known for providing a quick source of energy. Proteins are made up of amino acids and are crucial for building and repairing tissues, as well as various biological functions. Vitamins are organic compounds that are required in small amounts to support normal physiological function but are not classified as macronutrients like fats, carbohydrates, or proteins. Therefore, understanding the category of fats as lipids highlights their unique properties and functions within various biological systems.
