Hi all
I have a solution which I guess to have glucose in it, I have added benedict to it, and the color just got darker, and after heating it up to 90 ^oC, it didn't showed any brown participate (the appreance didn't change at all) but when I diluted it with some water and added bendeict, and heating, it showed some brown participate.
can anyone tell me what does it mean? And does my solution contain glucose or not
Thanks
