hi all! I was just thinking about organic compound indicators, and biuret solution for proteins crossed my mind. I know that it can be used to qualitatively tell the presence of proteins (peptide linkages) with a colour change. But is there a way that biuret solution can be used to take quantitative measurements??? ie) spectrophotometry, or is the reaction exothermic allowing a temperature measurement (not quite sure) Hope to receive some thoughts! thx!
