  • Enzymes of the Digestive System
    • Protease
      • pH : 8
      • Site of action : Small intestine
      • Substrates : Peptides
      • Site of production : Small intestine wall
      • Products : Amino acids
    • Pancreatic amylase
      • pH : 8
      • Site of action : Small intestine
      • Substrate : Starch / amylose
      • Site of production : Pancreas
      • Products : Sugars
    • Lipase
      • pH : 8
      • Site of action : Small intestine
      • Substrate : Lipids
      • Site of production : Pancreas and cells in small intestine wall
      • Products : Fatty acids and glycerol
    • Salivary amylase
      • pH : 8
      • Site of action : mouth
      • Substrate : Starch / amylose
      • Site of production : Salivary glands
      • Products : Sugars
    • Protease
      • pH : 2 (acid produced by the stomach acidifies food)
      • Products : Polypeptides and amino acids
      • Site of action : Stomach
      • Substrate : Proteins
      • Site of production : Cells in stomach wall
    • Protease
      • pH : 8 (bile from the liver neutralises acidic food in the duodenum)
      • Site of action : Small intestine
      • Substrate : Protein and polypeptides
      • Site of production : Pancreas
      • Products : Polypeptides and amino acids
