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 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!
