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]
It is often used in place of Fehling's solution to detect the presence of reducing sugars and other reducing substances. [2] Tests that use this reagent are called Benedict's tests. A positive result of Benedict's test is indicated by a color change from clear blue to brick-red with a precipitate.
The CPT code set describes medical, surgical, and diagnostic services and is designed to communicate uniform information about medical services and procedures among physicians, coders, patients, accreditation organizations, and payers for administrative, financial, and analytical purposes.
N-acetyl-β-d-glucosaminidase (EC 3.2.1.30; EC 3.2.1.52) is a mesophilic hydrolase that specifically hydrolyzes N-acetyl-glucosides. The enzyme is found across a wide variety of marine and terrestrial creatures with the primary function of breaking down oligosaccharides in the presence of water.

It reacts with a reducing sugar to form 3-amino-5-nitrosalicylic acid, which can be measured by spectrophotometry to determine the amount of reducing sugar that was present. [8] Some sugars, such as sucrose, do not react with any of the reducing-sugar test solutions. However, a non-reducing sugar can be hydrolyzed using dilute hydrochloric acid ...
Sucrose is a non-reducing sugar, so will not test positive with Benedict's solution. To test for sucrose, the sample is treated with sucrase. To test for sucrose, the sample is treated with sucrase. The sucrose is hydrolysed into glucose and fructose , with glucose being a reducing sugar , which in turn tests positive with Benedict's solution.
