Protein Chemistry Protein Tests: Biuret Test. Students are told this is a general test for proteins, not amino acids, and that a similar color is formed with all proteins. They are to put 10 drops of water, a 2% amino acid mixture (e.g. Difco's Casamino Acids), 2% egg albumin, or 2% gelatin in four separate tubes and add 5 drops of 3 M NaOH to each.

- Biuret Reagent. The biuret test uses an alkaline mixture, or reagent, composed of potassium hydroxide and copper sulfate. The normal color of biuret reagent is blue. The reagent turns violet in the presence of peptide bonds -- the chemical bonds that hold amino acids together.iuret Reagent.

Tests for the detection of Bence-Jones Protein Tests for the detection of Bence-Jones Protein. Bradshaw Test. The urine specimen is treated with 1 or 2 drops of 33 per cent acetic acid to bring the pH down to 4.8 to 5.0, centrifuged clear, and diluted 1:1 with water. The diluted urine is layered carefully over concentrated HCl in a test tube.

- Fructosamine is a compound that is formed when glucose combines with protein. This test measures the total amount of fructosamine (glycated protein) in the blood. Glucose molecules will permanently combine with proteins in the blood in a process called glycation.Affected proteins include albumin, the principal protein in the fluid portion of blood (serum), as well as other serum proteins and hemoglobin, the major protein found inside red blood cells (RBCs).The more glucose that is present in the blood, the greater the amount of glycated proteins that are formed.erum proteins are present in the blood for a shorter time, about 14 to 21 days, so glycated proteins, and the fructosamine test, reflect average glucose levels over a 2 to 3 week time period.

- Enzymes are complex proteins that facilitate chemical changes in every part of the body. Your body needs enzymes to function. The CPK isoenzymes test is a way to measure the levels of an enzyme called creatine phosphokinase (CPK) in your blood. CPK can be broken down into three distinct parts: 1  CPK-1 comes mainly from the brain and lungs. 2  CPK-2 is mainly from the heart. 3  CPK-3 is from skeletal muscle.

What is the chemical test of protein? The biuret test tests for peptide (protein) bonds. In a test with a protein containing substance, a Copper(II) ion is reduced to Copper(I) which forms a compound with the nitrogen and carbon atoms of the peptide (protein) bonds in an alkaline (pH above 7) solution. If the solution goes to a purply-violet colour, proteins have been detected.

What Is Normal Amount of Protein in Urine? Urine dipstick testing is one method of measuring urine protein levels. Your kidneys continuously filter your blood, excreting waste products while holding back proteins and other important molecules. Healthy kidneys normally allow almost no protein to be lost in the urine.

Protein Chemistry R Group Tests: Xanthoproteic Acid Test. Students are told that this is a chemical test for specific functional groups in amino acid side chains that gives a color with only two of the twenty amino acids, tyrosine and tryptophan. Depending which is present, formation of a yellow or orange color is a positive test.
