Will methionine give a positive Biuret test?
The answer is no. Not sure why at the moment but a question on my homework for biology lab asks why did lysine not react to the biuret's solution. If I had to guess it would be because Biuret's test is for peptide bonds in proteins and, lysine is just an amino acid not an actual protein, hence no peptide bonds. This is what I have concluded from just thinking about it. Not one hundred percent sure.
