Question:
A, B and C are three biomolecules. The results of the tests performed on them are given below:
$\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ are respectively:
Correct Option: , 2
Solution:
Molisch's test is used to check the presence of carbohydrates while Barfoed test is used for detecting the monosaccharides. Biuret test is used to detect the peptide bonds. Therefore, $\mathrm{A}$ and $\mathrm{B}$ (monosaccharide) are carbohydrates while $\mathrm{C}$ is a protein.
