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.
What else can I help you with?
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 glutamic acid give a positive biuret test?
Amino acids doesn't react with the biuret reagent.
Will lipids give positive result from Benedict's solution?
No, lipids will not give a positive result with Benedict's solution. Benedict's test is used primarily to detect reducing sugars, such as glucose and fructose, by forming a colored precipitate when heated in the presence of these sugars. Lipids do not contain the necessary functional groups that react with Benedict's reagent, so they do not produce a color change.
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.
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.
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.
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.
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.
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.
Will lipids give positive result from Benedict's solution?
No, lipids will not give a positive result with Benedict's solution. Benedict's test is used primarily to detect reducing sugars, such as glucose and fructose, by forming a colored precipitate when heated in the presence of these sugars.

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 Alanine give a negative Biuret test?
Yes, alanine will give a negative Biuret test. The Biuret test is used to detect the presence of proteins, which are made up of long chains of amino acids. Since alanine is a single amino acid, it will not give a positive response in the Biuret test.
Would albumin give a positive biuret test?
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.
Did gelatin give positive result with xanthoprotic test?
yes,it give positive test
