Topics 3.1 +3.2 - Carbohydrates, Lipids and Proteins and Enzymes

All Carbohydrates are made up of units of sugar
- Carbohydrates that contain only one unit of sugar (eg Glucose) or two units of sugar (eg Sucrose) are referred to as Simple Sugars
- Complex Carbohydrates (eg Starch and Cellulose) are long chains of simple sugar units bonded together
Lipids are molecules consisting of three molecules of fatty acids joined to one molecule of glycerol
Protein molecules are made up of long chains of amino acids
- These long chains are folded to produce a specific shape that enables other molecules to fit inside the protein
- Proteins act as structural components of tissues such as muscles, hormones, antibodies and enzymes
Enzymes are biological catalysts
- Catalysts increase the rate of…
