Question

A, B and C are three biomolecules. The results of the tests performed on them are given below : Molisch’s Test Barfoed Test Biuret Test A Positive Negative Negative B Positive Positive Negative C Negative Negative Positive A, B and C are respectively

(A) A=Lactose B=Glucose C=Albumin
(B) A=Lactose B=Glucose C=Alanine
(C) A=Lactose B=Fructose C=Alanine
(D) A=Glucose B=Sucrose C=Albumin

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, A and B (monosaccharide) are carbohydrates while C is a protein.
