  1. Biological Detergents
    1. Protein and fat digesting enzmes
      1. Lipase
        1. Protease
        2. Break down animal/plant matter
          1. Stains
            1. Food
              1. Blood
              2. More effective at lower temperatures
                1. eg. 30C
            2. Changing foods
              1. Proteins in baby food
                1. Pre-digested
                  1. Easier to digest
                  2. Proteases
                  3. Starch syrup to sugar syrup
                    1. Carbohydrases
                    2. Glucose to fructose
                      1. Isomerase
                        1. Sweeter
                          1. Less needed
                            1. Slimming products
                      2. Industry
                        1. Catalyse reactions
                          1. Don't need high temp. or pressure
                          2. Advantages
                            1. Specific to each reaction
                              1. Saves energy
                                1. Lower cost
                                2. Work for long time
                                  1. Can be continually used after initial cost
                                  2. Biodegradable
                                    1. Less environmental pollution
                                  3. Disadvantages
                                    1. Allergies
                                      1. Sensitive so can denature
                                        1. Conditions must be tightly controlled
                                        2. Expensive to produce
                                          1. Contamination can affect reaction
