Which sample gives a negative Biuret test and why?
Gelatin and egg albumin.
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.
Which sample gives a negative Biuret test and why?

What type of food will give a negative Iodine test and a positive Biuret Solution test?
An iodine test is used to test for the presence of starch (or polysaccharides, specifically amylose or amylopectin). A Biuret solution test is used as an indicator for peptide bonds within proteins. Therefore, if you get a negative iodine test and a positive Biuret test, you would probably be testing a animal food source (beef, chicken, pork). Overall, any food that doesn't have starch present within it would be appropriate to use. Hope this helps!
