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.

It depends on who takes a speed test. It takes a millon years to finish one.
A water bath is used in Benedict's test and Millon's test to provide a gentle and uniform heat to the mixture. This heat helps to speed up the reaction between the reagents and the substances being tested (glucose in Benedict's test and proteins in Millon's test), leading to a more reliable and accurate result. Additionally, the water bath allows for better temperature control, reducing the risk of overheating and potential degradation of the sample.
Yes, because casein is one of the protein that makes up milk. And when milk is denatured (by heat, or by any means), the denatured protein is tyrosine-which is the only protein positive for millon's test.
If both Biuret and Millon's tests give a positive result, it suggests the presence of proteins in the sample. Biuret test is specifically for proteins containing peptide bonds, while Millon's test is used for identifying proteins with tyrosine residues. The positive results from both tests provide strong evidence for the presence of proteins in the sample.
Millon's test is given by any compound containing a phenolic hydroxy group. Consequently, any protein containing tyrosine will give a positive test of a pink to dark-red color. The Million reagent is a solution of mercuric and mercurous ions in nitric and nitrous acids (CAUTION: MILLON'S REAGENT IS HIGHLY TOXIC AND HIGHLY CORROSIVE). The red color is probably due to a mercury salt of nitrated tyrosine.

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.
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.
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.
