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.

An example of a positive 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.
It was first introduced as a method to detect reducing substances in urine by James B. Sumner [2] and has since been widely used, for example, for quantifying carbohydrate levels in blood. [3] It is mainly used in assay of alpha-amylase. However, enzymatic methods are usually preferred due to DNS's lack of specificity. [4]
In organic chemistry, Fehling's solution is a chemical reagent used to differentiate between water-soluble carbohydrate and ketone (>C=O) functional groups, and as a test for reducing sugars and non-reducing sugars, supplementary to the Tollens' reagent test. The test was developed by German chemist Hermann von Fehling in 1849. [1]
Molisch test (using α-napthol) indicating a positive result (see purple ring). Molisch's test is a sensitive chemical test, named after Austrian botanist Hans Molisch, for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid or hydrochloric acid to produce an aldehyde, which condenses with two molecules of a phenol (usually α-naphthol, though other ...
Menopause can cause changes in your oral health. A dentist explains what changes you can expect from menopause and what you can do to combat them.
The rapid furfural test is a chemical test used to distinguish between glucose and fructose.The rapid furfural test is similar to Molisch's test but uses concentrated hydrochloric acid instead of concentrated sulfuric acid and the solution is boiled. [1]
