They all contain carbon bonded to other elements.

Explanation:

An organic molecule is a molecule that has bonded to other elements, such as oxygen, nitrogen, and more. There are some exceptions though, such as coal #(C)#, and carbon dioxide #(CO_2)#.

In carbohydrates, proteins, and fats, there's always some sort of carbon-hydrogen or carbon-oxygen bond, and since there're a lot of them, we consider those molecules to be organic.
