There's an old saying, "You are what you eat." In some senses, this is literally true! When we eat food, we take in the large biological molecules found in the food, including carbohydrates, proteins, lipids (such as fats), and nucleic acids (such as DNA), and use them to power our cells and build our bodies. Dive into the different types of macromolecules, what they are made up of, and how they are built up and broken down.
