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]
Alpha-hydroxy ketones are also called acyloins. [1] They are commonly formed by condensation or reductive coupling of two carbonyl (C=O) compounds or oxidation of ketones. The simplest such compound is hydroxyacetone. If the alcohol is primary, alpha-hydroxy ketones give a positive Fehling's test. Beta-hydroxy ketones are a type of aldol.
The symptoms of ketoacidosis are variable depending on the underlying cause. The most common symptoms include nausea, vomiting, abdominal pain, and weakness. [ 1 ] [ 2 ] Breath may also develop the smell of acetone as it is a volatile ketone that can be exhaled.
Additionally, ketone bodies can be anti-inflammatory. [19] Some kinds of cancer cells are unable to use ketone bodies, as they do not have the necessary enzymes to engage in ketolysis. It has been proposed that actively engaging in behaviors that promote ketogenesis could help manage the effects of some cancers. [6]

Test for ketonuria using Bayer Ketostix reagent strips. Urine testing is the most common method of testing for ketones. Urine test strips utilize a nitroprusside reaction with acetoacetate to give a semi-quantitative measure based on color change of the strip. Although beta-hydroxybutyrate is the predominant circulating ketone, urine test ...
The ketone which is present is mostly beta-hydroxybutyrate rather than acetoacetate resulting in only a weakly positive nitroprusside test. [2] People usually do not present with high blood sugar or sugar in the urine. [2] This can cause false negative results when testing urine ketones as they only measure acetoacetate.
The chemotherapy drug 5-FU can be toxic to some people with cancer. A quick, cheap test can show if chemo is safe for a patient, but few doctors order it. ... of the drug and definitive symptoms ...
