What organic compound does biurets test for?
proteins
Which chemical test shows the presence of an enzyme in a biological washing powder?
biurets test is the biochemical test for enzymesan enzyme is a protein and as the biochemical test for proteins is biurets,, its the same
Why does glycine test positive on biurets amino acid testing?
It shouldn't test positive. The Biuret test is only positive for a peptide or protein with 2 or more peptide bonds. Glycine is an individual amino acid. You'll see the blue from the Cu2+ with Glycine, but that's a negative result. A violet color is the positive.
If Biuret and Millon's test give positive result what is the conclusion?
The conclusion is that the sample contain proteins.
What is the Biurets test?
The Biurets test is used to identify if there are proteins present in a substance. The bond between the amino group and the carboxyl acid group on adjacent amino acids in a protein is a peptide bond. When the Biuret reagent (1 percent solution of copper sulfate) is added to a solution containing peptide bonds, the solution turns a violet color. The violet color is a positive test for the presence of protein. The more intense the color, the greater the number of peptide bonds that react. Hence, if it turned purple, then there are proteins, but if it stayed blue, then no proteins are present. Mostly it is used to check for enzymes which are made of proteins.
Why does albumin and pepsin test positive for protein?
Albumin and pepsin are both proteins, the test for proteins was positive.
What is the procedure of Gerhardt's test?
Gerhardt's test is a test for detecting the presence of proteins in a sample. To perform the test, nitric acid is added to the sample, followed by the addition of silver nitrate solution. A white flocculent precipitate forms if proteins are present, indicating a positive result.
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.
What is the positive result for sakaguchi test?
A red color is the positive result>
How does biuret solution test for protein?
Proteins are made of peptide bonds which is the target of reaction for biuret test. It's not truly specific for proteins; biuret itself also gives a positive result (hence the name of the test). However, proteins are fairly common and biuret (and similar peptide-containing compounds) are relatively rare.
Did gelatin give positive result with xanthoprotic test?
yes,it give positive test
Will a pregnancy test show positive if I miscarried?
A pregnancy test can show a positive result if you have miscarried. There is still enough hormone in your body to produce a positive result.
