Question

2. Do you think free amino acids will give a positive result with biuret test ? why?​

Answer 1

Answer:

Proteins can be detected through the use of the Biuret test. Specifically, peptide bonds (C-N bonds) in proteins complex with Cu2+ in Biuret reagent and produce a violet color. A Cu2+ must complex with four to six peptide bonds to produce a color; therefore, free amino acids do not positively react.
