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.
No, phenol would not give a positive result with Millon's test. Millon's test specifically detects phenolic compounds that have a hydroxyl group attached to a benzene ring, but phenol itself lacks the necessary structural modifications (like being part of a phenolic compound such as tyrosine) to react positively. The test is primarily used to identify the presence of tyrosine and similar amino acids, which undergo a specific reaction to form a red complex.
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.
same principle for latex methd
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.
