monomers and polymers

• monomers -

  the smaller units from which larger molecules are made from
• polymers -

  the larger units made from lots of monomers joined together
• examples of monomers-

  monosaccharides, amino acids, nucleotides
• examples of polymers -

  proteins, DNA, polysaccharides
• condensation reaction -

  joins two molecules together with the formation of chemical bond and the elimination of a water molecule
• hydrolysis reaction -

  breaks a chemical bond between two molecules and involves the use of a water molecule
