They are all biomolecules.


There are 4 types of biomolecules: carbohydrates, lipids, proteins, and nucleic acids. They are called as such because they are present in living organisms.

Cellulose, a polysaccharide ( poly meaning many, and saccharide referring to sugar), is classified as a carbohydrate. It is found in the cell wall of plants. Nucleic acids are molecules found in the nucleus and help with genetic material, like what DNA does for us. Keratin is a protein associated with structure, and is found in our hair and nails.
