  2. Seliwanoff's test - Wikipedia

    en.wikipedia.org/wiki/Seliwanoff's_test

    Seliwanoff’s test is a chemical test which distinguishes between aldose and ketose sugars. If the sugar contains a ketone group, it is a ketose. If a sugar contains an aldehyde group, it is an aldose. This test relies on the principle that, when heated, ketoses are more rapidly dehydrated than aldoses.

  3. List of purification methods in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_purification...

    Adsorption removes a soluble impurity from a feed stream by trapping it on the surface of a solid material, such as activated carbon, that forms strong non-covalent chemical bonds with the impurity. Chromatography employs continuous adsorption and desorption on a packed bed of a solid to purify multiple components of a single feed stream. In a ...

  5. Nuclear magnetic resonance spectroscopy of carbohydrates

    en.wikipedia.org/wiki/Nuclear_magnetic_resonance...

    Carbohydrate NMR spectroscopy is the application of nuclear magnetic resonance (NMR) spectroscopy to structural and conformational analysis of carbohydrates.This method allows the scientists to elucidate structure of monosaccharides, oligosaccharides, polysaccharides, glycoconjugates and other carbohydrate derivatives from synthetic and natural sources.

  6. List of sugars - Wikipedia

    en.wikipedia.org/wiki/List_of_sugars

    This is a list of sugars and sugar products. Sugar is the generalized name for sweet, short-chain, soluble carbohydrates, many of which are used in food. They are composed of carbon, hydrogen, and oxygen. There are various types of sugar derived from different sources. Generally speaking, chemical names ending in -ose indicate sugars.

  7. Characteristic property - Wikipedia

    en.wikipedia.org/wiki/Characteristic_property

    A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample being observed is large or small. Thus, conversely, if the property of a substance changes as the sample size changes, that property is not a characteristic ...

    en.wikipedia.org/wiki/White_sugar

    Grains of white sugar White sugar is often sold and used as cubes A bowl of white sugar. White sugar, also called table sugar, granulated sugar, or regular sugar, is a commonly used type of sugar, made either of beet sugar or cane sugar, which has undergone a refining process. It is nearly pure sucrose.

  9. Chemical property - Wikipedia

    en.wikipedia.org/wiki/Chemical_property

    Material properties, both physical and chemical, can be viewed as supervenient; i.e., secondary to the underlying reality. Several layers of superveniency [clarification needed] are possible. Chemical properties can be used for building chemical classifications. They can also be useful to identify an unknown substance or to separate or purify ...
