Hey.

okay.. the biuret test is a test for peptide bonds. when CuSO4 is added to KOH, an alkaline solution, nitrogen atoms from the peptide bond forms a purple compound with the Cu2+ ions. hope this helps! read it in a text book.

What is the results biuret test for egg albumin?

The biuret test for egg albumin would give a positive result, showing a violet color change, indicating the presence of peptide bonds in the protein structure. This test is used to confirm the presence of proteins in a solution based on the color change that occurs in the presence of peptide bonds.


Does phenol give a positive biuret test?

No, phenol does not give a positive biuret test. The biuret test is used to detect the presence of proteins, not phenol. Phenol is a type of organic compound that does not contain the peptide bonds that the biuret test reacts with.


Would glucose give a positive result with the Biuret test?

No, glucose would not give a positive result with the Biuret test. The Biuret test is specific for detecting proteins, not sugars like glucose. It works by reacting with peptide bonds in proteins to form a colored complex.


Will albumin give positive result to Benedict test?

No, albumin will not give a positive result to the Benedict test. The Benedict test is used to detect the presence of reducing sugars such as glucose, fructose, and maltose, not proteins like albumin.


If Biuret and Millon's test give positive result what is the conclusion?

If both Biuret and Millon's tests give a positive result, it suggests the presence of proteins in the sample. Biuret test is specifically for proteins containing peptide bonds, while Millon's test is used for identifying proteins with tyrosine residues. The positive results from both tests provide strong evidence for the presence of proteins in the sample.

Will glutamic acid give a positive biuret test?

Amino acids doesn't react with the biuret reagent.


Does pepsin test positive in biuret test?

Pepsin does not test positive in the biuret test. The biuret test is used to detect the presence of proteins in a solution, which contain peptide bonds. Pepsin is an enzyme that breaks down proteins into smaller peptides, so it does not give a positive result in the biuret test.


How many of these chemical groupings must be present in a molecule to give a positive biuret test?

At least two peptide bonds must be present in a molecule to give a positive biuret test. The biuret reagent interacts with peptide bonds in proteins, forming a colored complex that can be detected visually.


Will albumin give positive result to Benedict test?

No, albumin will not give a positive result to the Benedict test. The Benedict test is used to detect the presence of reducing sugars such as glucose, fructose, and maltose, not proteins like albumin.


How many chemical grouping must be present in a molecule to give a positive Biuret Test?

You must have at least two, those that will form the peptide linkage (NH2 and COOH) since Biuret test is for detecting peptide linkages.


Will lipids give positive result for biuret est?

No, lipids will not give a positive result for the Biuret test. The Biuret test is specifically designed to detect the presence of proteins, as it reacts with peptide bonds in amino acids. Lipids, which are primarily composed of fatty acids and glycerol, do not contain these peptide bonds and therefore do not react in this test.

The positive results from both tests provide strong evidence for the presence of proteins in the sample.


Will gelatin give a positive Biuret test?

yes Gelatin will have a positive biuret test. this is because it has an amide group which bends over the copper ion giving the colour pink or violet off to the visual eye.
