What colour is a millon's reagent when mixed with egg albumin after heating?
A Millon's reagent mixed with egg albumin and heated would turn red. This color change occurs due to the reaction between the phenolic compounds in Millon's reagent and the tyrosine residues in the protein.
What components of protein give a positive test with Millon's reagent and on what is this reaction based?
The phenolic and tyrosine residues in proteins give a positive test with Millon's reagent. This reaction is based on the oxidation of phenolic groups by mercuric nitrate in the reagent to form a red-colored complex.
What is chemical composition of kf reagent?
KF reagent typically refers to Karl Fischer reagent, which is used for moisture determination. It usually consists of an iodine compound, a sulfur dioxide-based titrant, a base (such as pyridine), and a solvent (often methanol or ethanol). The specific chemical composition may vary depending on the manufacturer and type of Karl Fischer reagent.
What is the structural formula of millon's reagent?
Millons reagent is not a compound but a mixture. It is made by dissolving mercury in nitric acid. There is a variant which Millons, Coles reagent which is a LITTLE safer as it uses sodium nitrite and sulfuric acid with mercury. The chemistry is a bit obscure- some say that it involves mercurous ions and nitrous acid. The end result is a nice red color.
What amino acid will yield a positive result with millon's test?
Tyrosine. Millon's Reagent-a solution that is usually made by dissolving mercury in concentrated nitric acid and diluting with water and that when heated with phenolic compounds gives a red coloration used as a test especially for tyrosine and proteins containing tyrosine. (from merriam-webster's medical dicitonary) i hope this will help you.

What colour is a millon's reagent when mixed with egg albumin after heating?
A Millon's reagent mixed with egg albumin and heated would turn red. This color change occurs due to the reaction between the phenolic compounds in Millon's reagent and the tyrosine residues in the protein.
What is million reagent?
You probably mean Millon's reagent. Millon's reagent is a solution of mercury in nitric acid which is used as a test for the amino acid tyrosine. Since proteins contain tyrosine, it is also used as a test for protein. When the test solution is boiled with Millon's reagent a white precipitate (solid) is produced which coagulates and turns red.
What components of protein give a positive test with Millon's reagent and on what is this reaction based?
The phenolic and tyrosine residues in proteins give a positive test with Millon's reagent. This reaction is based on the oxidation of phenolic groups by mercuric nitrate in the reagent to form a red-colored complex.
What color is million's reagent?
Millon's reagent is red in color, due to the presence of mercuric sulfate and mercuric nitrate in nitric acid solution.
Is egg albumin positive to millon test?
Yes, egg albumin is positive for the Millon's test due to the presence of aromatic amino acids like tyrosine, which react with Millon's reagent to produce a red color.
When was Albert Nasse born?
Albert Nasse was born in 1878.
When did Albert Nasse die?
Albert Nasse died in 1910.
When did Christian Friedrich Nasse die?
Christian Friedrich Nasse died in 1851.
When was Christian Friedrich Nasse born?
Christian Friedrich Nasse was born in 1778.
When was Ward-Nasse Gallery created?
Ward-Nasse Gallery was created in 1970.
What is responsible for the color reaction for the millon'e test?
The color reaction in the Millon's test is due to the formation of a red complex between phenolic hydroxyl groups of tyrosine and Millon's reagent (mercury in nitric acid solution). This complex forms as a result of the oxidative reaction between the tyrosine residues and the reagent.
