  1. Caught By a Kiss

  2. Enzymes • Speed up or catalyze a reaction • Help to digest food, make copies of DNA

  3. Amylase • Main digestive enzyme found in human saliva • Catalyzes breakdown of starch

  4. Amylase continued • Found in pancreas and salivary glands • IMPORTANT: epithelial lining of mouth is often sloughed off into saliva (source of DNA)

  5. Amylase • Starch + Iodine  blue/purple color • Starch (polysaccharide) + amylase  disaccharides • Amylase degrades starch? • Disaccharides (degraded starch) + iodine  clear to yellow color
