Carbohydrates - carbon molecules (carbo) combined with water (hydrate).
Life based on carbon
Carbon atoms readily form bonds with other carbon atoms.
Allows a sequence of carbon atoms of various lengths to be built, form a backbone with other atoms attached.
Life is based on carbon and a small number of other chemical elements.
The making of large molecules
Monomer = individual molecule that make up chains of molecules together.
Polymer = longer chain of molecules (monomers)
Biological molecules e.g. carbohydrates and proteins are ofter polymers.
Most made up of just carbon, nitrogen, oxygen and hydrogen.
