Rates of Reaction

Catalysts - Enzymes - Classifications and Uses.

In the process of digestion, enzymes are used to break down
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 (starch)
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 sugar syrup
and glucose syrup into fructose syrup.

7) Industrial Processes.
