Answer:
The sample contains protein.
Explanation:
Biuret test is a test used to determine or assay for proteins in a solution. When the biuret reagent is added to a solution and it turns blue after 2 minutes, it means that the solution contains protein.
Benedict’s test is used to determine the presence of sugar (reducing sugar) in a solution. When it turns brick red, it means there is the presence of reducing sugar in large quantity.
From the question, since the solution turned blue on addition of Biuret reagent and was also blue on addition of Benedict’s reagent (the reagent is usually blue), it means that the solution contained just proteins excluding reducing sugars.
