How do carbohydrates work with other macromolecules?

How do carbohydrates rely on each other?

Macromolecules are polymers made in the cell by linking small chemical sub-units together in a specific sequence. Nucleic acids, proteins and other macromolecules such as polysaccharides interact with each other and with small molecules through weak chemical bonds.

Explanation:

Carbohydrates are the sugars and their polymers. Together differently cellulose has a different shape, and therefore different properties, than starch or glycogen.
