- Enzymes
- Definition - Catalysts produced by living things.
- Every enzyme is unique and fits into one substrate
- They rate they work at changes depending on the temperature and Ph
- If too high a temperature or too acidic or alkaline it destroys the enzymes shape and denatures
- Types of enzymes
- Amalase
- Turns starch into maltose (sugars)
- Made in the salivary glands, pancreas and small intestine
- Protease
- Turns proteins into Amino acids
- Made in the stomach (called pepsin), pancreas and small intestine
- Lipase
- Turns lipid (fats and oils) into fatty acids)
- Made in the pancreas and small intestine
- Bile
- Neutralises HCl acid in stomach to make conditions alkaline for enzymes to work
- Also emulsifies fats into droplets, for bigger surface area and enzymes to work faster
- Produced in Liver and stored in gall bladder then released to small intestine
- Amalase
- Uses in industry
- Biological detergents
- Made of proteases and Lipases to break down stains
- Work best at 30-40C
- Made of proteases and Lipases to break down stains
- Foods
- Baby food
- Protease to help babies digest easier
- Sweetners
- Turns glucose sugars into fructose sugers
- Baby food
- Advantages
- Specific enzymes for the reaction you want
- Work at lower temperatures
- Work for a long time
- They are biodegradabe, so good for the environment
- Disadvantages
- Allergies
- Enzymes can denature at a slight change in temperature.
- Expensive to product
- Biological detergents
