Monomers & Polymers

• Define monomer


  smaller repeating units that join together to form larger molecules (polymer)
• Define polymer


  molecules formed when many monomers join together
• Define condensation reaction


  A reaction that forms a chemical bond between two molecules and eliminates a water molecule
• Define hydrolysis reaction


  A reaction that breaks a chemical bond between two molecules and uses a water molecule
• Examples of monomers


  • Monosaccharides
  • amino acids
  • nucleotides
• Examples of polymers


  • Polysaccharides
  • Proteins
  • DNA / RNA
• glycosidic bond


  A covalent bond between a carbohydrate molecule and an hydroxyl group on another molecule, resulting from a condensation reaction
• hydrogen bond


  A weak chemical bond between the positive charge on a hydrogen atom and the negative charge on the atom of an adjacent molecule
• peptide bond


  A covalent bond between 2 amino acids, resulting from a condensation reaction
• ionic bond


  A moderate chemical bond formed by the electrostatic attraction between two oppositely charged ions
• phosphodiester bond


  A covalent bond between two nucleotides , resulting from a condensation reaction
