What are macromolecules?

Macromolecules are a long molecules that make almost all functions performed by living matter. There are four types of macromolecules: carbohydrates, lipids, proteins and nucleic acids. Although they have different structures and functions, are all composed of long, complex chains of molecules called polymers, with subunits called monomers. They are joined together in a process known as dehydration synthesis in which a covalent bond is formed between two monomers through the release of a water molecule.
Here is a good example of what that are!!!!‼↓↓↓↓
