Abstract. Disaccharides, one of the most important groups of biomolecules, are often given little attention in undergraduate biochemistry laboratories. Due to their closely related structures it is often difficult to distinguish experimentally between monosaccharides. An undergraduate experiment for the biochemistry laboratory is detailed in which students identify a disaccharide among a group of four, based on the results of Benedict’s test, reactivity with an enzyme, and identification of the monosaccharides present using an HPLC equipped with a charged aerosol detector.
