|MadSci Network: Biochemistry|
I am a 7th grade life science teacher. As part of our unit on biological molecules, we use some chemcial indicators to test for the presence of protein, simple sugar and carbohydrates. We use iodine or Lugol's solution for starches and Benedict's heated to identify the presence of simple sugars. My student's and I are flumoxed when not one sample of table sugar we tried tested positive with either the Lugol's or Benedict's. I've asked around and nobody has been able to explain this to us. Can you guys help? Best Regards, Susan
Re: Why doesn't a solution of granulated sugar heated with Benedict's turn red?
