Fehling's test is used to distinguish between the presence of aldehydes and ketones in carbohydrates as ketone sugars except alpha-hydroxy-ketone do not react in this test. Fehling's test is performed in medical facilities to detect the presence of glucose in urine. This helps to identify whether the patient has diabetes or not The all new Fehling kerrison tray (catalog # UCA-3S) is constructed from lightweight anodized aluminum to provide a safe, convenient way to maximize the lifespan of your Fehling kerrisons.With easily accessible handles and a two-point latch system for the removable lid, the UCA-3S offers protection in the sterilization chamber, the OR, and everywhere in between

Fehling's test is used for the detection of reducing sugars or differentiate between water soluble carbohydrates or ketone functional groups. The test was developed by German Chemist Hermann von Fehling in 1849. In the test Fehling's solution is used to get the result
The principle behind Fehling′ test is basically based on the reducing property of monosaccharide and disaccharides, which in turn depends on the presence of free keto or an aldehyde group. This test is performed by adding a few drops of sugar solution to a mixture of Fehling′s A solution (i.e., CuSO 4 ) and Fehling′s B solution (i.e., KOH.

Principle of Fehling's test: Fehling's test is one of the sensitive test for detection of reducing sugars. Fehling's reagents comprises of two solution Fehling's solution A and solution B. Fehling's solution A is aqueous copper sulphate and Fehling's solution B is alkaline sodium potassium tartarate ( Rochelle salt)

Fehling's solution is used as a chemical test used to differentiate between water-soluble aldehyde and ketone functional groups, and as a test for monosaccharides.The test was developed by German chemist Hermann von Fehling in 1849. [1]. Fehling's solution is always prepared fresh in the laboratory. It is made initially as two separate solutions, known as Fehling's A and Fehling's B.

In medicine, Fehling's solution is used to detect glucose in urine as a part of detecting diabetes. Fehling's Reagent is used in the breakdown of starch where it changed to glucose syrup and maltodextrins (a polysaccharide used as a food additive). This is done in order to measure the amount of reducing sugar
One of the most popular tests used for the estimation or detection of reducing sugars and non-reducing sugars is the Fehling's test. The test developed by German chemist H.C. Von Fehling is also used to differentiate between ketone functional groups and water-soluble carbohydrates. Fehling's Solutio
For example, fructose gives a positive test with Fehling's solution as does acetoin. Two solutions are required: Fehling's A uses 7 g CuSO 4.5H 2 O dissolved in distilled water containing 2 drops of dilute sulfuric acid. Fehling's B uses 35g of potassium tartrate and 12g of NaOH in 100 ml of distilled water
Hermann von Fehling (9 June 1812 - 1 July 1885) was a German chemist, famous as the developer of Fehling's solution used for estimation of sugar. Biography. Hermann von Fehling was born in Lübeck. With the intention of taking up pharmacy he entered Heidelberg University about 1835
