IGCSE BIOLOGY 
UNIT 4: BIOLOGICAL MOLECULES

Before you start you can look back at 8A Nutrition.

This unit builds on your previous knowledge about  

If you only remember one thing:

FATS ARE MADE OF FATTY ACIDS AND GLYCEROL, PROTEINS ARE MADE OF AMINO ACIDS AND STARCH IS MADE OF SIMPLE SUGARS.

This is the second of the 21 Biology units:
