WebbThe two general tests for identifying proteins are the Biuret test and the Ninhydrin test. All proteins give a positive result in these tests. If a molecule does not test positive in them, … WebbThe biuret method is based on the fact that proteins (and, as a rule, all substances containing two or more peptidic bonds) react with copper to form a colored complex whose absorption ( λmax =454 nm), in the presence of excess copper, is proportional to the amount of protein present. The reagent is obtained by dissolving 1–5 g of copper (II ...
