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 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.
What is the reagent used to test proteins?
Buiret Reagent
What reagent is used to detect glucose in a solution?
You are not supposed to use buret reagent to detect sugar carbohydrates in a solution. Buret reagent is used to detect proteins. Try using iodine ( I2KI)

How do manufacturers decided which reaction to use in excess in a chemical reaction?
The cheaper reagent is usually the reagent that is used in excess. This procedure is purely for economic reasons.
What is the difference between Benedict's Reagent and Biuret Reagent?
Benedicts reagent is used to check reducing sugars , it need hat to work and gives red color when positive ,. While biuret reagent is for proteins .there is no need to use heat and gives purple , violet color when positive ..
