  • Most important biological molecules are polymers.

  • Polymers are made from smaller molecules called monomers.

  • Biological molecules are based on the element carbon. It has the ability to form 4 bonds with itself or with other elements.

  • The bonds that hold monomers together are often formed by condensation reactions.

  • Organisms constantly take in a range of chemicals, using them to make other substances that they need.

Chains of repeated smaller molecules called monomers. Smaller molecules that join together to make larger polymers. When the bond is formed, water is removed.
