Rates of Reaction
Catalysts - Enzymes - Classifications and Uses.
In the process of digestion, enzymes
are used to break down
large food molecules into smaller soluble molecules.
Enzymes are classified according to the type of food they digest.
Enzymes are classified as carbohydrase, lipase or protease.
Carbohydrase - changes carbohydrate
into sugars (glucose).
Lipase - changes
fat (lipid) into fatty
acids and glycerol
(in biology the posh word for "fat" is "lipid").
Protease - changes protein into amino acids.
Enzymes are used in
1) making alcohol (yeast)
2) making yoghurt and cheese (bacteria).
3) biological detergents (lipase and protease).
4) making soft-centred chocolates
5) making baby food
6) changing starch syrup into
and glucose syrup into fructose syrup.
7) Industrial Processes.
