Macromolecules inside of foods can be large polymers or small monomers How do these molecules from food get built into polymers and broken down into monomers in our bodies

Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts
