@hennaforeva im not sure what you mean, but specifically biuret tests for the presence of peptide bonds. Peptide bonds link each glucose molecule in a protein.
and, the fact that the video cam was zoomed onto the name of the reagent at 0:55 (sodium hydroxide) is very obvious that the hint was already given. what i mean is, that the student has wrongly switched up the order of reagents to be added to the sample. it should be sodium hydroxide first, followed by copper (II) sulphate. that's the simple answer to the question posed in the video.
