2024年5月22日 · This colorimetric chemical test used to detect the peptide bond using the Biuret reagent is called the Biuret test. It is also called Piotrowski’s reaction after the name of the Polish physiologist Gustaw Piotrowski who observed this phenomenon in 1857 and used it to detect proteins in samples.

The biuret test is a colorimetric test that helps detect specific proteins or peptide bonds in given analytes. It is followed by spectrophotometry for quantification. The test requires the use of a biuret reagent.
Biuret Test - an overview | ScienceDirect Topics
Biuret test is used to detect proteins in the sample. The peptide bonds of protein form a purple violet complex upon reaction with CuSO 4 in alkali condition. The intensity of the complex is directly proportional to the number of the peptide bond in the protein sample.
Biuret test - Definition and Examples - Biology Online
2023年3月3日 · The Biuret test is used to detect the presence of proteins in a sample. The test is founded on the idea that copper ions in an alkaline solution can form a complex with the peptide bonds in proteins, resulting in a change in color, from blue to violet.
