Condensation hydrolysis

  1. 1. IB Biology Hydrolysis and Condensation Reactions Hydrolysi s Condensation Glucose Maltose - a disaccharide made from two glucose molecules Glucose
  2. 2. Hydrolysis [ hydro (water) lysis (splitting) ] Splitting a chemical bond by the addition of water The hydrolysis of maltose using water produces two molecules of glucose
  3. 3. Maltose Molecule Glucose molecule Glucose molecule Drag the two glucose molecules out of the box below. This is what Hydrolysis does Can you see where the water molecule is added. OH to one and H to the other molecule. A Hydrolysis Reaction
  4. 4. e.g. A condensation reaction joins two glucose molecules to make a single maltose molecule and a water molecule. A condensation reaction is when two molecules are combined to form one single larger molecule, with the loss of a water molecule.
  5. 5. Maltose Molecule Glucose molecule Glucose molecule Drag the two glucose molecules into the box below to form a disaccharide Can you see the water molecule which is produced ? A Condensation Reaction
  6. 6. Ribose Sugar - forms the backbone of DNA Fructose Sugar Important in fruit and sucrose Glucose Maltose - a disaccharide made from two glucose molecules Biological Molecules can be joined together to make bigger molecules using condendation reactions
  7. 7. The twisted branched structure of Glycogen Cellulose - a flat polysaccharide - this diagram shows just nine glucose rings Very large Biological Molecules are made using condensation reactions
  8. 8. Hydrolysis Condensation Disaccharide e.g. Maltose *** Triglyceride Molecule *** Dipeptide Monosaccharides e.g. Glucose *** Three Fatty Acids & a Glycerol molecule *** Amino Acids Condensation and Hydrolysis Reactions ... opposites of each other.
  9. 9. Triglyceride Molecule Three Fatty Acids & a Glycerol molecule Hydrolysis Condensation Condensation and Hydrolysis Reactions also form Lipids.
  10. 10. An unsaturated fatty acid Glycerol A saturated fatty acid A Triglyceride - 3 Fatty Acid chains and 1 Glycerol Molecule Water Highlights the parts of each molecule which react together Each condensation reaction produces a water molecule
  11. 11. A Dipeptide Molecule Two Amino Acid Molecules Hydrolysis Condensation
  12. 12. This highlighted area shows the peptide bond OH group The H from one amino acid joins the OH from another. This links the two amino acids forms a peptide bond and a molecule of water. H Drag this amino acid to make the two yellow highlights join together and see for yourself. Condensation and Hydrolysis Reactions form proteins
  13. 13. Three IB Style Questions List three examples of Hydrolysis reactions in biological cells. ................................................................................................... ................................................................................................... ...................................................................................................
