Hydrolysis is ordinarily effected in the presence of acids (acid hydrolysis) or alkalies (alkaline hydrolysis). it was waited for 10 minutes so that the hydrolysis reaction can proceed. Hydrolysis is an organic chemical reaction that involves adding water to break apart molecules. Sucrose indirectly produces a positive result with Benedict's reagent if heated with dilute hydrochloric acid prior to the test, although after this treatment it is no longer sucrose. On the other hand, an oxidation or a reduction followed by hydrolysis, will determine the monosaccharide whose reducing group has remained free. When left in aqueous solution, the ester linkage can hydrolyze to produce a dipeptide and methanol, neither of which is sweet. The two monosaccharides are held together by a glycosidic bond (α1-β2), between C-1 of α-glucose and C-2 of β-fructose.
