What chemical reagent of protein?
Biuret reagent is used to test for protein in urine. It is a common test that students in biology class perform. Urine is added to a test tube, followed by approximately the same amount of Biuret reagent. If the solution turns lavender this means that there are proteins present in the urine.
Is biuret test suitable to test the presence of proteins in the urine?
Yes, the biuret test will indicate the presence of peptides. If it turns violet, it is a positive result.
Does pepsin test positive in biuret test?
No
How many of these chemical groupings must be present in a molecule to give a positive biuret test?
you should have at least 2 of these,to obtain a positive result in Biuret's test. because biuret test is a test used to detect if there is peptide linkages.
Will glutamic acid give a positive biuret test?
Amino acids doesn't react with the biuret reagent.
How can you prove that milk contains protein?
Dry it to a powder and perform the the biuret test on this powder.
Caseine in biuret test?
Casein form a purple compound in the biuret test.
