WebThe presence of protein is tested by the Biuret test for proteins. The Biurette reagent made of sodium hydroxide and copper (II) sulphate helps in determining the presence of protein in a sample. ... We used Biuret's reagent to detect the presence of proteins in solution. The reagent is pale blue when pure, but when mixed with proteins, ... WebThe biuret test employs a reagent made up of potassium hydroxide and copper sulphate. The biuret reagent has a blue colour under normal conditions. If peptide bonds are present, it changes colour to violet. The peptide bond is the chemical bond that connects amino acids. Copper sulphate and sodium hydroxide are two other biuret reagent substitutes. WebThe Biuret reagent is made of potassium hydroxide (KOH) and copper (II) sulfate (CuSO 4), together with potassium sodium tartrate (KNaC 4 H 4 O 6 ·4H 2 O).
