  2. Reducing sugar - Wikipedia

    en.wikipedia.org/wiki/Reducing_sugar

    The common dietary monosaccharides galactose, glucose and fructose are all reducing sugars. Disaccharides are formed from two monosaccharides and can be classified as either reducing or nonreducing. Nonreducing disaccharides like sucrose and trehalose have glycosidic bonds between their anomeric carbons and thus cannot convert to an open-chain ...

  3. 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 ...

  4. Monosaccharide - Wikipedia

    en.wikipedia.org/wiki/Monosaccharide

    Monosaccharides (from Greek monos: single, sacchar: sugar), also called simple sugars, are the simplest forms of sugar and the most basic units from which all carbohydrates are built. Chemically, monosaccharides are polyhydroxy aldehydes with the formula H-[CHOH] n-CHO or polyhydroxy ketones with the formula H-[CHOH] m-CO-[CHOH]

  5. Carbohydrate synthesis - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_synthesis

    When connecting the monosaccharides, the oligosaccharides need to be reducing in order to sequentially connect the glycosyl units. The monosaccharides, in nature prefer ɑ-linkages due to anomeric effect , [ 1 ] but the disaccharides with ɑ-linkages are non-reducing thus deactivating the consequent connection of the monosaccharides. [ 15 ]

  6. Oligosaccharide nomenclature - Wikipedia

    en.wikipedia.org/wiki/Oligosaccharide_nomenclature

    An oligosaccharide has both a reducing and a non-reducing end. The reducing end of an oligosaccharide is the monosaccharide residue with hemiacetal functionality, thereby capable of reducing the Tollens’ reagent, while the non-reducing end is the monosaccharide residue in acetal form, thus incapable of reducing the Tollens’ reagent. [2]

  7. Disaccharide - Wikipedia

    en.wikipedia.org/wiki/Disaccharide

    Reducing disaccharides, in which one monosaccharide, the reducing sugar of the pair, still has a free hemiacetal unit that can perform as a reducing aldehyde group; lactose, maltose and cellobiose are examples of reducing disaccharides, each with one hemiacetal unit, the other occupied by the glycosidic bond, which prevents it from acting as a ...

    The basics: Low sugar, emphasis on fish over meat, healthy oils and fats. Focused on reducing inflammation that may cause weight gain and health problems. Positives: Eliminates processed foods.

  9. Fehling's solution - Wikipedia

    en.wikipedia.org/wiki/Fehling's_solution

    Fehling's test can be used as a generic test for monosaccharides and other reducing sugars (e.g., maltose). It will give a positive result for aldose monosaccharides (due to the oxidisable aldehyde group) but also for ketose monosaccharides, as they are converted to aldoses by the base in the reagent, and then give a positive result.
