How to test for starch, glucose and protein using reagent?

Hello,

1. To a test tube, add 40 drops of liquid to be tested.

2. If testing more than one liquid, label each test tube with a marker.

3. Add 3 drops of Biuret reagent solution to each test tube. Shake gently to mix. 

4. Note any color change. Proteins will turn solution pink or purple.
