A Sample had reagent solutions used: Iodine solution (no change), Biuret solution (pink), Benedict's solution (yellow) and Pure water (control, no change).
There were 2 colour changes.
The sample was found to contain trace amounts of glucose and amino acids. Based on the colour changes observed for this sample, provide a Biochemical explanation for these findings.
Demonstrate biochemistry-based principles behind reagent tests (that can result in more than one observable colour change depending on the amount of solute in the sample).

A pink biuret test indicates shorter polypeptide chain.
A yellow Benedict's test means 0.5-1.0% sugar is present.
A yellow Benedict's test means 0.5-1.0% sugar is present.
What biochemistry-based principles behind reagent tests results in more than one observable colour change?
(depending on the amount of solute in the sample)

I am not an organic chemist; I don't know that answer.
