Question about Biuret reagent lab

Post by PianistSk8er » Wed Nov 09, 2005 5:47 am

We recently completed a lab dealing with Biuret reagent and testing it on a protein (test) and distilled water (control).

We also tested it on other substances (glucose, sucrose, starch and oil), which all tested negatively. These are all carbohydrates, except for the oil. Other than using them as another control group, I see no purpose in this test. The lab questionnaire asks why we needed to test these substances and I'm fresh out of ideas, other than the abovementioned. Got any clues?

Any help appreciated! Thanks!

I agree that they would serve as controls. However i can't think of anything else. how much must you write?
