Enzymes

protein- long chains of amino acids

proteins can be;

• tissue such as muscle
• hormones
• antibodies
• ENZYMES

enzymes are biological catalysts which speed up reactions

enzymes can :

• biuld large molecules from many smaller ones
• change one molecule into another
• break down large molecules

factors affecting enzyme actions-

• heat- if its too hot, the enzymes will stop working and will become denatured
• pH- if its wrond the enzyme will change shap

digestion- the break down of large, insoluble molecules into smalller soluble molecules

Amylase--> produced by the salivary gland, pancreas and small intestine--> digestion of strach into sugars in the mouth and small intestine

Protease--> produced by the stomach--> break down of protein to amino acid in the stomach and small intestine

Lipase--> produce in the pancreas and small intestine--> breakdown of lipads to fatty acids and glycerol

Isomerase--> convert glucose to fructose syrup 

biological detergents contain lipase and protease to  digest food stains

advantages:

• effective at removing stains
• can be used at low temperatures- saves energy and reduces cost
• cost of energy and equipment can be reduced

disadvantages:

• allergic reactions
• may enter water ways
• costly to produce
• some fabrics such as wool will be digested by protease
