monomers and polymers

• monomers are the smaller units from which larger molecules are made from
• polymers are molecules made from a large number of monomers joined together
• 3 examples of monomers in biology are: monosaccharides, amino acids and nucleotides
• a condensation reaction is when two molecules join together to form a chemical bond, involving the elimination of a water molecule
• a hydrolysis reaction breaks a chemical bond between 2 molecules and involves the use of a water molecule
