Rates of Reaction

Catalysts - Enzymes - Chocolates and Baby Food.

Enzymes are used to make some soft-centred chocolates.

An enzyme called invertase will convert a sugar called sucrose
into smaller sugar molecules called glucose and fructose.
The breaking down of some sucrose molecules
causes the chocolate to become softer and sweeter
(fructose is particularly sweet).

Proteases may be used in making baby food.
Large protein molecules can be partly broken down into amino acids.
This process happens naturally during digestion.
Using enzymes to pre-digest the protein in food
makes it easier for digestion by the baby.
