Study Notes
Monomer and Polymer Definitions
- Monomer means "one." Think of words like monobrow or monocle.
- Polymer means "many." Think of polygons which have many sides.
Monomers and Polymers in Chemistry
- Monomers are single, simple units.
- Polymers are chains of monomers bonded together.
Example of Monomers and Polymers
- Lego bricks are a visual representation of monomers and polymers. Individual bricks are monomers, and a joined series of bricks are polymers.
Biological Molecules – Glucose Test
- Glucose is a simple sugar.
- Carbohydrates are made of many small sugar molecules called monomers (simple sugars). Polysaccharides (polymers) are long chains of these monomers
- A polymer is a carbohydrate molecule such as starch or glycogen (many linked monomers)
- A monomer is a simple sugar such as glucose.
Benedict's Test for Glucose
- Purpose: Test for simple sugars like glucose.
- Materials Needed: Food sample, Benedict's solution, test tube, water bath.
- Procedure:
- Prepare a sample of the food.
- Put 5 ml of the food sample into a test tube.
- Add 5 ml of Benedict's solution using a syringe and mix.
- Place the test tube in a water bath at 80°C for 10 minutes.
- Record the colour change after 10 minutes.
- Results:
- Negative result (no glucose): blue
- Low glucose: green/yellow
- Medium glucose: orange
- High glucose: brick red
Important Notes for Benedict's Test
- Always wear goggles during the experiment.
- Follow the procedure step-by-step.
