What colour will the biuret test give if its positive?

In: Biology, Chemistry [Edit categories]

Answer:

The biuret test is a chemical test used for detecting the presence of peptide bonds. In a positive test, a copper(II) ion is reduced to copper(I), which forms a complex with the nitrogens of the peptide bonds in an alkaline solution. A violet color indicates the presence of proteins.

Copy and pasted straight from wikipedia. Did you do any research at all before asking this? do your own homework.

just sayin, wikipedia is unreliable, but yea in this case its right. the solution will turn pink/violet.

Will gelatin give a positive Biuret test?
yes Gelatin will have a positive biuret test. this is because it has an amide group which bends over the copper ion giving the colour pink or violet off to the visual eye.
Why will proteins give a positive result with biuret test and be faintly positive for ninhydrin?
