digestion and enzymes

• enzymes are a type of catalyst - they speed up chemical reactions without being used up themselves
• amino acids used to make proteins
• enzymes in baby food : added to pre digest proteins, makes it easier for babies to absorb amino acids to use for growth
• in biological washing powder : enzymes are added to washing powder to remove food stains on clothes. they break down the stains into water soluble substances that can dissolve
• enzyme nutrient broken down product

  proteas -> protein -> amino acids
• enzyme nutrient broken down product

  carbohydrase -> starch -> sugars
• enzyme nutrient broken down product

  lipase -> lipids -> fatty acids and glycerol
• how enzymes break down a stain caused by a greasy chip - the grease stain is caused by fat, so the lipases break down lipids into fatty acids and glycerol. They also break down the stain into water soluble substances that can dissolve
• advantages of using enzymes on washing powders: helps save water , money and the planet. Remove stains on delicate fabrics and work at low temps
• disadvantages : can cause damage to the fabric and set off alergies
