What is the structure for each macromolecule (what does each one look like?)

Within cells, small organic molecules are joined together to form larger molecules. These large macromolecules may consist of thousands of covalently bonded atoms and weigh more than 100,000 daltons. The four major classes of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

there’s no image attached but i can if you want: )
