  2. CA State Standards • Students know large molecules (polymers), such as proteins, nucleic acids, and starch, are formed by repetitive combinations of simple subunits. • Students know amino acids are the building blocks of proteins. • Students know the bonding characteristics of carbon that result in the formation of a large variety of structures ranging from simple hydrocarbons to complex polymers and biological molecules.
  3. Definitions Monomer - A molecule that can combine with others of the same kind to form a polymer. Polymer - A substance that has a molecular structure built from a large number of similar units (monomers) bonded together.
  4. CH20H OH OH H OH OH Carbohydrates Monomer - The simple sugars Glucose, sucrose, fructose (and many others) Polymer - The complex carbohydrates. Starch and Cellulose CH20H are long chains of simple CH20 H OH sugars OH OH OH CH20H OH OH OH

  6. Proteins Peptide bond Polymer - When many amino acids bond together to create long chains, the polymer is called a protein (it is also called a polypeptide because it contains many peptide bonds).
