- The systematic name of this enzyme class is "'biuret amidohydrolase " '.
- Why would water be included as a test subject in a Benedicts test or biuret reagent test?
- He was biuret hydrate, where he completed most of the calculations for the crystal structure by hand.
- Will cystine, proline, leucine, water and egg albumin change color with the biuret reagent test?
- And he obtained a patent for the use of biuret for animal feed ( Kamlet, 1956 ).
- Hofmeister also argued for peptide bonds based on the biuret reaction observed with all proteins but never with free amino acids.
- The test is named so because it also gives a positive reaction to the peptide-like bonds in the biuret molecule.
- It is a common precipitant in protein crystallography and is also an ingredient in the Biuret reagent which is used to measure protein concentration.
- Despite its name, the reagent does not in fact contain biuret ( ( H 2 N-CO-) 2 NH ).
- The term " biuret " also describes a family of organic compounds with the functional group-( HN-CO-) 2 N -.
- The biuret reaction can be used to assess the concentration of proteins because peptide bonds occur with the same frequency per amino acid in the peptide.
- Since biuret has the formula NH 2-CO-NH-CO-NH 2, that suggested the presence of similar peptide bonds in proteins.
- The reagent is commonly used in the biuret protein assay, a colorimetric test used to determine protein concentration by UV / VIS spectroscopy at wavelength 550 nm.
- I know Biuret Reagent turns violet in the presence of protein, but amino acids make up proteins, so will they change color ? Preceding talk ) 00 : 50, 8 October 2010 ( UTC)
- Other experiments you can do with copper sulfate solution are : add ammonia to get a dark blue solution which can dissolve cotton, add biuret to get a different dark blue solution, add a base like sodium bicarbonate to make a precipitate.
- The water-soluble BCA / copper complex absorbs much more strongly than the peptide / copper complex, increasing the sensitivity of the biuret test by a factor of around 100 : the BCA assay allows to detect proteins in the range of 0.0005 to 2 mg / mL ).
- I didn't dig for the best sources, but to quote, " Dipeptides, single amino acids ( except serine and threonine ), urea, and ammonia give blue solutions, which are negative tests " and in a historical source, [ http : / / books . google . com / books ? id = ztDqAAAAMAAJ & pg = PA11 " According to Schiff, the red coloration is caused by the formation of a copper potassium biuret compound.
