  2. Benedict's reagent - Wikipedia

    en.wikipedia.org/wiki/Benedict's_reagent

    Generally, Benedict's test detects the presence of aldehyde groups, alpha-hydroxy-ketones, and hemiacetals, including those that occur in certain ketoses. In example, although the ketose fructose is not strictly a reducing sugar, it is an alpha-hydroxy-ketone which results to a positive test because the base component of Benedict converts it ...

    Although there were already a number of wet-chemical detection methods to identify sugars, such as the Fehling or Benedict test, those analyses could only differentiate between reducing and non-reducing sugars. Since both glucose and lactose molecules have an aldehyde group in the open-chain form, the result was positive in both cases. Only the ...

  5. Ketose - Wikipedia

    en.wikipedia.org/wiki/Ketose

    All monosaccharide ketoses are reducing sugars, because they can tautomerize into aldoses via an enediol intermediate, and the resulting aldehyde group can be oxidised, for example in the Tollens' test or Benedict's test. [3] Ketoses that are bound into glycosides, for example in the case of the fructose moiety of sucrose, are nonreducing ...

    The Chemex filter should be rinsed with hot water to remove any paper taste. After dumping the water, ground coffee is added to the rinsed paper filter. The coarse grind will resemble kosher salt for the best flavor. [9] Hot water (93–96 °C (199–205 °F) is then poured through the coffee and filter, depositing brewed coffee into the flask.
