A Level Biology Revision "Testing for Starch, Protein and Lipids"

You can find all my A Level Biology videos fully indexed at www.freescienc...
In this video, we look at how to carry out the chemical tests for starch, protein and lipids. I take you through the procedure involved and show you the positive and negative results. In the next video, we look at how to test for reducing sugars and non-reducing sugars.
